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.
Willian to Manchester United
Chelsea's Brazilian winger could light up the World Cup this summer and Jose Mourinho is reportedly trying to steal a march on other potential suitors by securing his signature at the end of this season. The Guardian report than Juan Mata will make way for the 29-year-old, who could cost the Manchester club £30 million. Chelsea paid the same price to Anzhi Makhachkala in 2013, while the winger is under contract until 2020.
Djibril Sidibe to Manchester United
Manchester United are reportedly looking to solve their left-back problem by signing Sidibe from Monaco. Ashley Young has been filling in admirably while Luke Shaw remains out of favour, but the club are looking for an upgrade going into next season, according to French outlet Le10Sport. The 25-year-old Frenchman seems to fit the bill and, although a natural right-sided full-back, he has played on either flank.
Sokratis to Arsenal
Borussia Dortmund defensive stalwart Sokratis is a target for Arsenal, according to Gazzetta dello Sport. The Greece centre-back has also been linked with moves to Manchester United and Juventus in recent weeks, but Arsene Wenger's side have reportedly thrown their hat into the ring for a player whose contract expires next year. Wenger may see the 29-year-old as a replacement for Per Mertesacker, while the player is thought to be looking for a new challenge after five seasons in Dortmund.
Antoine Griezmann to Juventus
The Italian champions look set to join the scramble for one of the best players in the world, with AS reporting that the Frenchman is top of Juventus' list of transfer targets. Griezmann has been linked to some of the biggest clubs in Europe, with Barcelona and Manchester United also rumoured to be in the mix, but Massimiliano Allegri's side seem ready to spend big on a player they see as someone who can help them get over the line in big Champions League ties.
Luke Shaw to Barcelona
The Manchester United left-back is set to leave the club this summer in order to find regular playing time, and La Liga leaders Barcelona are reportedly planning a loan offer for the Englishman. A temporary deal to test the waters may suit the Catalan club, but there could be other sides offering a permanent move which may suit Jose Mourinho more. The Daily Mail report that Shaw would be used as back-up to Jordi Alba at the Camp Nou, so it remains to be seen whether the player fancies a move to Spain.
