Transfer Rater: Iago Aspas to Real Madrid, Gary Cahill to Galatasaray

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.

Rafinha to Real Betis

Barcelona look like they're trying to trim the fat on their squad, with Rafinha heavily linked with a move to Real Betis. It would be a loan move, according to reports from Mundo Deportivo, but Barcelona are reportedly looking for the deal to include an obligation to buy the player at the end of the loan. Neither side want to wait, so something should happen soon.

Iago Aspas to Real Madrid

The transfer window always throws up some odd rumours, but Aspas has performed well since his disappointing spell at Liverpool -- well enough that Real Madrid are reportedly interested. According to Super Deporte, Aspas is seen as a cheaper and more available alternative to €120m Valencia forward Rodrigo and could be available for around €40m.

Adrien Rabiot to AC Milan

Rumours have surrounded Rabiot all summer -- his existing contract expires in 2019 and, reports suggest, he has no interest of renewing it at Paris Saint-Germain. Both Barcelona and Real Madrid have been interested, but Calcio Mercato reports that AC Milan are looking for a midfielder just like Rabiot.

Gary Cahill to Galatasaray

The arrival of possession-focused Maurizio Sarri always had the potential to be a threat to Cahill's chances of making the first team at Chelsea, and the defender has reportedly been given permission to talk with other clubs about a move. Fotomac report that Galatasaray have been told they can discuss a potential deal, with the England international's contract expiring next summer.

Sergej Milinkovic-Savic to Juventus

With the transfer windows now closed in England and Italy, Juventus and Manchester United transfer target Milinkovic-Savic won't be moving this summer. But Turin newspaper La Stampa have reminded their readers about Juventus' interest in the Lazio midfielder, hinting that there may still be a move to be made once the window opens again in January.
