Things change in the blink of an eye in football. The Football Whispers Index takes the latest transfer rumours and gives them a score out of five; the higher the score, the more realistic and reliable the Whisper.
Here are today's top five emerging whispers. And keep an eye on Transfer Talk for all the latest gossip.
Donny van de Beek to Chelsea
The Blues, and a number of other potential suitors across Europe, have received a boost in their pursuit of Ajax midfielder Donny van de Beek. The 21-year-old, much like teammate Frenkie de Jong, is a highly regarded prospect but has only started twice for the Dutch club in the Eredivisie this term. And Van de Beek's agent, Guido Alberts, told Voetbal International the midfielder would consider a transfer if his situation doesn't change.
Hirving Lozano to Tottenham
Tottenham Hotspur are considering launching a move for Mexico star Hirving Lozano after he caught the eye of their scouts, according to the Mirror. The 23-year-old winger, who was linked with Barcelona in the summer, has impressed once again for this term PSV, who are in Spurs' Champions League group. The report says the Dutch side value Lozano at £25 million and are braced for bids to be made next summer.
Lorenzo Pellegrini to Manchester United
While the future is uncertain for Jose Mourinho at Manchester United, the club have identified Roma midfielder Lorenzo Pellegrini as a transfer target, according to Gazzetta dello Sport. The Italy international's contract has a £30m release clause, which the Red Devils are certainly capable of paying. Roma, however, hope to agree a new deal with the 22-year-old which would see that clause increased.
Jake Clarke-Salter to Borussia Dortmund
After the success of bringing Jadon Sancho to Germany, Borussia Dortmund are considering launching a move for another England youngster: Jake Clarke-Salter. According to Goal, BVB have been impressed by the young defender, who is currently on loan at Vitesse Arnhem and may launch a move next summer. However, the report claims Bayer Leverkusen, Fulham and Burnley are also interested in the England Under-21 international.
Alex Telles to Liverpool
Liverpool sent a representative to Porto's Champions League win against Galatasaray on Wednesday night to check the progress of Alex Telles, according to Sport Witness. The Reds are one of many Premier League clubs linked with the left-back, who has a £40m release clause in his contract, and could bring him to Anfield to provide competition for Andrew Robertson.
