Sporting Lisbon have denied that they will sell Manchester United target William Carvalho in the summer, amid claims in the media. Various newspaper reports have claimed that a deal has been agreed between Man United and Sporting for the sale of Carvalho for a reported 37 million, triggering the 21-year-old’s buy-out clause. Sporting are reluctant to sell the midfielder, whose contract runs up until 2018, despite the possibility of cashing in on Carvalho with a host of top European clubs, including Chelsea and Real Madrid along with Man United. Should any interested side make a bid that matches Carvalho’s buy-clause then the Portuguese club would be powerless to prevent the in-demand midfielder from leaving, however, Sporting president Bruno de Carvalho has moved to rubbish reports that a deal has been agreed for the sale of the Portugal international.“We are calm although every day there are stories in the papers appearing about the sale of our player,” the club’s supremo told TVI 24.“Sporting is not a club exclusively just for the sale of players. If a club pays ˆ45 million (37 million) then it is not necessary to speak, but I think William does not want to leave Sporting.“At the moment it is more likely that he will sign a new deal. Personally, I say that the kid is content at Sporting.”Watch Barcelona v Atletico Madrid in the Champions League on Tuesday. 24 hour Sky Sports day pass for only 9.99.
