Here are today's top five emerging whispers. And keep an eye on Transfer Talk for all the latest gossip.

Jack Wilshere to AC Milan

The English midfielder is yet to agree a new contract with Arsenal, and AC Milan are one of a number of options for him should he decide that his future lies away from North London. According to Calciomercato, Milan manager Gennaro Gattuso has been impressed with the midfielder's outings in the Europa League this season, and is looking to add him to his squad for next season.

Fernando Torres to DC United

The Major League Soccer outfit are looking to bring in a big-name striker when the secondary transfer window opens in July, as reported by Goal. Former Manchester United and Juventus forward Carlos Tevez has been mentioned as a possible marquee signing, but Torres is believed to be the more realistic option as his contract at Atletico Madrid expires this summer. The 34-year-old has said he will leave the club, with the possibility of returning in a non-playing capacity in the future.

Alex Sandro to Manchester United

Jose Mourinho wants a first-choice left-back to replace the out of favour Luke Shaw, and the Brazilian is top of his list according to the Manchester Evening News. The Juventus full-back has been targeted by Premier League clubs in the past, including Chelsea, but the Manchester United manager is determined to bring Sandro to Old Trafford this summer to solve a long-running issue at left-back.

Leon Bailey to Manchester City

The Bayer Leverkusen forward has attracted attention from across Europe this season, with Pep Guardiola's side the latest to show interest in the Jamaican. Goal report that there is a possibility Chilean keeper Claudio Bravo could move in the opposite direction as part of the deal, and that Manchester City want to tie up two big transfers before the World Cup gets underway in June. Napoli's pass master Jorginho is one, and Bailey could be the other.

Leonardo Bittencourt to Tottenham

The Cologne midfielder is expected to leave the club -- who are set for relegation from the Bundesliga -- and he's looking at the possibility of a move to the Premier League, according to Bild. Tottenham have been scouting the player this season and are ready to make a £7 million bid in the summer. Werder Bremen, Hoffenheim and Monaco are also interested according to the reports.
