Transfer Rater: Christian Pulisic to Real Madrid, Ismaila Sarr to Man Utd

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.

Daniele Rugani to Chelsea

Chelsea will make an improved bid of over £45 million to Juventus for Rugani, according to Goal, after an initial offer was turned down earlier this month. Fali Ramadani is representing the west London club in the talks, and the Macedonian has a reputation for getting these deals done, especially in Serie A. Goal report that Ramadani met with Juventus sporting director Fabio Paratici in Milan, when the initial offer was knocked back, but they are confident of completing a deal with an increased offer.

Leonardo Bonucci to Juventus

AC Milan's interest in Juventus striker Gonzalo Higuain has reportedly put the Turin club in a strong position to re-sign centre back Bonucci. With Rugani close to a move to Chelsea, Massimiliano Allegri is looking for another centre-back, and the 31-year-old club favourite fits the bill. Gazzetta dello Sport believe that any past tensions between Allegri and Bonucci can be overcome, and a deal can be done.

Christian Pulisic to Real Madrid

Real Madrid are believed to be considering other options should they fail to land Eden Hazard or Neymar in this transfer window, and Borussia Dortmund's Pulisic has emerged as a target, according to the Daily Mail. The American international is valued at around £60m, and has been impressive in preseason, scoring twice against Liverpool last weekend. Real join Chelsea, Bayern Munich, and Barcelona in pursuit of the teenager.

Ismaila Sarr to Man Utd

Manchester United are leading the race for Senegal international Sarr, according to The Sun, amid interest from numerous Premier League sides. England's top clubs have all reportedly scouted the 20-year-old, who can play across the front line but mainly operates on the wing. Currently at Ligue 1 side Rennes, Sarr caught the eye at the World Cup despite Senegal's exit in the group stages, and his performances have intensified the interest in him.

Domagoj Vida to Arsenal

Arsenal are the latest club to be linked with Croatian international Vida, with Turkish newspaper Milliyet claiming a bid has arrived from north London. The centre-back partnered Dejan Lovren as Croatia made it to the World Cup final, which led to rumours that Liverpool wanted to unite the pair at club level. However, recent reports suggest Arsenal now look to be the likely destination should the 29-year-old move to the Premier League.
