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 for the summer. And keep an eye on Transfer Talk for all the latest gossip.
Henry Onyekuru to Arsenal
After months of uncertainty, Arsene Wenger has reportedly agreed a new two-year contract with Arsenal. The extension comes days after the Frenchman led his team to an impressive FA Cup final victory over Chelsea. Now, he appears determined to improve his squad ahead of next season, and Henry Onyekuru is one of his targets. According to the Daily Mail, the Gunners have agreed a £6.8 million fee for the 19-year-old forward with Belgian club KAS Eupen, though the player is yet to agree personal terms. The Nigerian scored 24 goals in 41 appearances in 2016-17.
Moussa Sissoko to Marseille
One year on from his sensational £30m move from Newcastle United to Tottenham Hotspur, Sissoko could be on the verge of leaving English football altogether. Ligue 1 side Marseille have been linked with a move for the player, who started just eight Premier League games for Spurs and failed to truly stamp his mark. Commenting on the situation, the midfielder told French sports daily L'Equipe: "I am 27 and I need to get to the [2018] World Cup. If a situation arrives where I can leave, I hope they don't cause problems. Everyone knows that I would prefer to stay in England but I have not closed the door on other leagues."
Divock Origi to Monaco
Monaco were one of the most entertaining sides in Europe throughout 2016-17, though their talented young squad could be picked apart this summer. Bernardo Silva has already left for Manchester City, and others could follow. However, French champions are keen to replace those that go, and Divock Origi is one potential addition. The Liverpool striker is reportedly being tracked by both Monaco and Lyon. Were he to join the former, he could team up with Kylian Mbappe and Falcao up front.
Carlos Bacca to Arsenal
Evidently, Arsenal are gunning for a new attacker and, according to the Daily Mirror, Carlos Bacca is one of their primary transfer targets. The Colombian earned a reputation as one of Europe's most fearsome strikers during a productive spell with Sevilla, but struggled for goals in his second campaign with AC Milan in Italy, hitting just 13 in 29 league outings.
Ruben Semedo to West Ham
West Ham United have emerged as the latest Premier League side considering a move for Sporting Lisbon defender Ruben Semedo. Newcastle and Southampton have also been linked with the player, who broke out in 2016-17 with some impressive displays in the Portuguese top tier. The 23-year-old is a centre-back who can also operate in defensive midfield. He is powerful, athletic and capable when bringing the ball out from the back, but he is also error-prone. And, while he signed a new deal with Sporting in March that included a release clause of €45m, his club are purportedly open to offers of around €20m.
