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.
Cenk Tosun to Besiktas
Turkish giants Besiktas reportedly want to bring Everton striker Tosun back to Istanbul as the 27-year-old has failed to shine at Goodison Park. Tosun moved to the Toffees last January for £27m and has scored six goals in 22 Premier League appearances, however has been inconsistent so far under Marco Silva. Talksport report that Besiktas are planning a loan move in January for their former striker.
Milan Skriniar to Manchester United
Jose Mourinho's search for a centre-back continues with attentions turning to Inter Milan defender Skriniar. Sourceshave told ESPN that Mourinho has requested the Slovakia international as a show of faith from the board that he has a long-term future at Old Trafford. At 23, Skriniar is also significantly younger than Mourinho's previous targets of Toby Alderweireld, Jerome Boateng and Diego Godin which should help convince the board.
Alessio Romagnoli to Manchester United
Also among Mourinho's targets to bolster his ailing backline, according to ESPN sources, is Milan centre-back Romagnoli, who is also 23. The Italian has previously been linked with Chelsea and the Rossoneri successfully agreed a new contract extension in August taking his current deal up to 2022. Should Mourinho be sufficiently backed in the market, however, Milan may have no choice but to accept an offer.
Harry Kane to Real Madrid
Madrid's poor start to the season, in which they have been winless and scoreless in their last four matches, has prompted president Florentino Perez to push for a marquee signing in attack. The failure to replace Cristiano Ronaldo in the summer has meant Kane is back in consideration for Los Blancos, according to El Confidencial. However, Real's director general Jose Angel Sanchez has also suggested RB Leipzig's Timo Werner as a more affordable alternative.
Jadon Sancho to Chelsea
Sancho's stunning start to the season for Borussia Dortmund has alerted the Premier League's finest, although the Bundesliga club will demand £100m for the English winger. The Sun claim that Chelsea, Arsenal, Manchester United, Liverpool and Tottenham are all monitoring the 18-year-old, who left City last year after turning down a contract. Dortmund, however, view Sancho as Ousmane Dembele's long-term replacement and have no plans to let him go.
