The transfer window for Europe's biggest clubs is open again. Transfer Talk has been scouring the world's media and setting our correspondents loose to see who could be heading to/out of your club this month.
TOP STORY: Chelsea enquire about Barcelona flop Coutinho
He's been at Barcelona for only a little over a year, but already things have turned sour for Philippe Coutinho.
The 26-year-old has not been able to force his way into Ernesto Valverde's side on a regular basis, starting just 10 La Liga fixtures this term.
Speculatively linked with Manchester United last week, the former Liverpool attacker could still be offered a Premier League lifeline, with a report from the Daily Express claiming Chelsea have asked after his availability.
The Londoners have been quoted a reported £100 million for Coutinho, who cost the Catalans £142m when he joined a year ago.

23.28 GMT: That'll do it for Sunday's edition of Transfer Talk! Join us tomorrow morning for a fresh slate of transfer news!
23.26 GMT: The Mirror reports that England legend Ashley Cole will return to his home country and play for Frank Lampard's Derby County.
According to sources, he will earn £10,000-per-week.
22.35 GMT: The Liverpool Echo report that Jurgen Klopp has admitted that he faces a "really difficult problem" regarding the right-back position due to a combination of injury and suspension troubles.
Could this be a sign that Liverpool are in the market for a new right-back before the end of the window?
21.58 GMT: football.london reports that Roman Abramovich has given the go ahead for Chelsea to sign Barcelona teenager Ilaix Moriba.
The 16-year-old is a product of the famous La Masia, and would represent a huge coup for Chelsea, seeing as they'd see the deal through at the expense of fellow Premier League heavweight Manchester City.
21.23 GMT: The Hull Daily Mail report that both Manchester United and Chelsea are hot on the trail of League Two sensation Antoine Semenyo of Bristol City.
The 19-year-old is currently on loan at Newport County and would command a fee of about £2 million.
20.45 GMT: Here's one that'll undoubtedly get fans, especially Real Madrid fans, salivating: talkSport reports that Kylian Mbappe refused to rule out the possibility of one day moving to Real Madrid from PSG.
Will that ever actually happen? He'll certainly cost a pretty penny, but Lord knows that Real Madrid's president Florentino Perez has never been shy about spending big.
20.17 GMT: According to the Birmingham Mail, Marouane Fellaini's mooted transfer either to AC Milan or Porto (both clubs were linked with the player) is off thanks to a calf injury that has ruled him out for up to a month.
19.39 GMT: The Birmingham Mail reports that Middlesbrough's Stewart Downing has been made available for transfer because he wants a better pay raise than the one he will likely receive.
His current contract states that he is due for a raise after making 150 appearances for the club. After coming on as a second-half substitute yesterday against Millwall, that number stands at 149. That said, he wants to go to a club that can give him the kind of pay raise he believes that he deserves.
18.27 GMT: MLS.com reports that the New York Red Bulls have rejected Club America's first bid for prized playmaker Kaku.
This comes as no surprise as Club America are seeking a replacement for Diego Lainez, who recently transferred to Real Betis in La Liga.
17.44 GMT: According to the Guardian, Manchester United full-back Matteo Darmian is the subject of advanced discussions between his parent club and Juventus, who want to take him to Turin on loan for the rest of the season.
The proposed deal would also include a £7.1 million clause to sign the player permanently in the summer.
17.13 GMT: Here's a transfer triangle of sorts that's been reported by The Mirror: Arsenal could be in line to secure the transfer of Atletico Madrid winger Gelson Martins...thanks to Chelsea.
The transfer of Alvaro Morata to Spain's capital would leave Martins surplus to requirements, leaving him open for the Gunners to pick him up.
However, there's an issue. Since manager Unai Emery said that the team can only make loan signings during this window, that leaves them at a disadvantage, one that Monaco manager and Arsenal legend Thierry Henry intends to exploit by also making a run at the Portuguese winger.
16.00 GMT: With Higuain on his way to Chelsea, AC Milan have reportedly acted quickly by securing Krzysztof Piatek as a replacement striker, according to the Guardian.
The paper reports that a €35m deal has been agreed between the Rossoneri and Genoa for the Poland international.
Piatek, 23, has scored 13 goals in 19 Serie A games so far this season.
14:40 GMT: Luka Modric was heavily linked with a move to Inter Milan, following his star turn at the World Cup.
However, the Croatian playmaker has now confirmed he intends to extend his Real Madrid contract.
"I have a year and a half left on my contract and I am calm, as that's a long time," Modric told reporters after scoring in Madrid's 2-0 win over Sevilla on Saturday.
"My desire is to stay here for more time. I am as happy as I was on the first day."
13.35 GMT: West Ham look set to keep hold of star striker Marko Arnautovic after his big-money move to China collapsed, according to the Mail on Sunday.
The paper reports that the Austria international's proposed £35m move to Guangzhou Evergrande is off.
Hammers boss Manuel Pellegrini explained Arnautovic's absence for Saturday's 2-0 defeat at Bournemouth by saying: "A manager must choose the players that work better during the week. Marko has his head on another issue so it wasn't a good idea for him to play.
"I don't think we need to continue talking about players that are not in the squad in this moment. We couldn't win and, if Marko Arnautovic didn't play, we have another player that must do it."
12.55 GMT: Gonzalo Higuain has been left out of AC Milan's squad to face Genoa on Monday as a loan move to Chelsea draws near.
Higuain, who is on loan to Milan from Juventus, is set to cut short his spell with the Rossoneri in order to move to the Premier League to be reunited with Maurizio Sarri, who he played for at Napoli.
Earlier in the week, sources told ESPN FC that the agreement will give Chelsea the option to either buy Higuain next summer or extend the loan for a further 12 months.

12.30 GMT: Inter Milan have confirmed their interest in Atletico Madrid defender Diego Godin -- ranked No. 3 among the world's centre-backs int he ESPN FC 100.
Godin, 32, had previously been linked with Manchester United, but as his Atletico contract gets closer to expiring in the summer it is Inter who have emerged as favourites to sign him.
Inter CEO is quoted by Calciomercato as saying: "I have to underline how Inter Milan has a very strong appeal, many players are looking for us and many agents knock at our door, which flatters us, because we represent a point of reference for many important players. We evaluate profiles of champions that we must not let go and Godin is one of them"
11.45 GMT: Paul Scholes is in talks with Oldham Athletic over the manager's position at the League Two club, sources have told ESPN FC, but no agreement is yet in place for the former Manchester United midfielder to take his first steps into management.
Scholes, who made 718 appearances for United during a 19-year career at Old Trafford, is involved in football as a part-owner of National League club Salford City along with several of his former Manchester United teammates.
Should he take the Oldham job, he would have to relinquish his role at Salford if the two clubs are in the same division next season.
But the former England international has made no secret of his desire to try his hand at management and sources have confirmed to ESPN FC that he is considering the opportunity to take charge of Oldham -- a team he watched as a youngster growing up in nearby Middleton.
Scholes, 44, saw Oldham suffer a 2-1 defeat against Macclesfield at Moss Rose on Saturday, but if he is prepared to succeed the sacked Frankie Bunn as manager at Boundary Park, he could be appointed in time for the FA Cup fourth-round clash at Doncaster Rovers on Saturday.
10.50 GMT: Borussia Dortmund sporting director Michael Zorc said midfielder Julian Weigl will stay in Dortmund this winter amid heavy links to Thomas Tuchel's Paris-Saint Germain on Saturday.
Weigl, 23, played an integral role in BVB's 1-0 win away to RB Leipzig that restored the Bundesliga leaders' six-point advantage over second-placed Bayern Munich, who had dismantled Hoffenheim 3-1 on Friday.
Asked about a potential move from Weigl to the Ligue 1 leaders, Zorc told German broadcaster ZDF: "Julian Weigl will stay in Dortmund," adding: "He has already played very well against Gladbach [as centre-back] before the winter break and once again showed a brilliant performance tonight -- especially when keeping in mind that he usually plays in midfield."
Sources told ESPN FC that Weigl, who played under Tuchel at Dortmund, remains PSG's top choice this month while PSG are looking for a replacement for Adrien Rabiot, who is still training with the reserves after refusing to sign a new contract. The pressure on sporting director Antero Henrique is increasing after midfielder Marco Veratti picked up an ankle injury in PSG's 9-0 win over Guingamp on Saturday.
10.15 GMT: A former fan favourite could be about to return to Arsenal in an upstairs role, according to the Sunday Mirror.
The paper reports that former Gunners winger Marc Overmars is a candidate to become the club's new technical director, following his success in a similar role at Ajax.
Overmars has helped develop young Dutch players such as Frenkie de Jong, Matthijs de Ligt and Justin Kluivert, as well as recruit and then sell stars such as Christian Eriksen, Toby Alderweireld and Davinson Sanchez.
The story comes after a source confirmed to ESPN FC that head of recruitment Sven Mislintat is set to leave Arsenal after a series of disagreements over the Gunners' organisational structure and transfer strategy
09.30 GMT: They may be the richest club in the world with two quality players in every position, but it seems Manchester City are not above bringing in players on loan if they need to.
According to the Sun on Sunday, Pep Guardiola's side may make a move to bring in Schalke and Germany midfielder Sebastian Rudy.
The report claims that City want the 28-year-old to provide cover for Fernandinho in central midfield, the area Guardiola has identified as the one where he needs more strength in depth.
City are looking at players such as Ajax's Frenkie de Jong, Wolves' Ruben Neves and West Ham's Declan Rice as permanent signings in the summer, but Rudy could help plug the gap until then.
PAPER TALK (Tom Bodell, Football Whispers)
Real Madrid's Silva service
If one man has benefitted from Kevin De Bruyne's injury woes at Manchester City this season, it's Portuguese schemer Bernardo Silva. The 24-year-old had to be patient after joining from Monaco in the summer of 2017 but has come into his own this term with the Belgian seeing limited action.
Real Madrid have taken note of Silva's fine form for Pep Guardiola's side and, according to the Daily Mirror, will make a move this summer.
The report in Sunday's edition goes on to claim the Spanish giants' interest could force the Premier League champions to open talks over a new deal. Silva is contracted until the summer of 2022.
Dortmund intent on keeping Sancho
Jadon Sancho has been one of the breakout stars of the season and a key player in Borussia Dortmund's remarkable title bid.
Naturally, talk of a big-money move has started to emerge. But BVB are adamant they will hold onto the teenage forward beyond the summer. Among those linked already are Manchester City -- the side he left to join Dortmund for just £7m just two summers ago.
"Jadon Sancho will stay with us in the next season," sporting director Michael Zorc told SportBild. "He has great quality and is a bet for the future, he will remain in Dortmund."
Emery drops hint over Suarez reunion
Arsenal boss Unai Emery has already admitted Arsenal can afford only to make loan signings this month, limiting their capabilities in the market.
However, the Star says one target who is available on loan is Barcelona midfielder Denis Suarez. The 25-year-old is known to Emery, having played under him at Sevilla and, handily, is well down the pecking order at the Camp Nou, meaning he would be allowed to leave this month.
Asked about the possibility of signing the Spanish midfielder following his side's 2-0 victory over Chelsea on Saturday, Emery said: "I know the club is working with different possibilities if [it] can help us for these four months for our competition."
Asked whether Suarez might be signed in time for his side's FA Cup fourth-round tie against Manchester United on Jan. 25, Emery replied: "I know it's a difficult window for the transfer market, and if a player is coming to help us I am happy. But the club is doing that and I am going to wait."
Football Whispers' top emerging whispers
Football Whispers' transfer algorithm gives the likelihood of rumours happening a score out of 5.
Weston McKennie to Liverpool: 2.8
Jurgen Klopp knows the Bundesliga better than most and could be about to return to his homeland to sign United States and Schalke powerhouse Weston McKennie, according to the Sun. The 20-year-old midfielder, who can also play at centre-back, could be available for around £20m.
Christian Eriksen to Chelsea: 1.5
While Harry Kane continues to dominate the headlines, the Danish playmaker struggles to get the credit he deserves for his quietly brilliant performances behind the England captain. But his quality has not gone unnoticed, with Chelsea joining Real Madrid in expressing an interest, according to the Daily Mirror.
Aaron Wan-Bissaka to Manchester City: 1.4
It's been a while since Wilfried Zaha and Nathaniel Clyne came through Crystal Palace's much-vaunted academy. Now the South Londoners have another talent on their hands in Wan-Bissaka. The 21-year-old has made the right-back spot his this season and, according to the Times, Manchester City are keen to swoop.
Carlos Vela to Barcelona: 1.2
The Mexico international was never a regular for Arsenal and finally left for Real Sociedad in 2012 after five loan spells away from the Emirates. Now 29, he spent last season in Major League Soccer with LAFC, bagging 14 goals and supplying 11 assists. According to ESPN Deportes, Vela is now a surprise loan target for Barcelona.
Hirving Lozano to Arsenal: 1.2
One of the stars of the World Cup as Mexico reached the round of 16 before crashing out -- as usual -- the PSV Eindhoven forward has carried his form into this season, scoring 11 goals in just 17 Eredivisie starts. That form, according to Tuttomercato, has prompted interest from Arsenal. The North Londoners face competition from Napoli, Chelsea and Real Madrid.
