Manchester United are keen on signing Freddy Adu if the Ghanaian-born American teenager can prove himself, Sir Alex Ferguson has confirmed.

Asked if he was interested in signing the midfielder, Ferguson said: 'I think so, he's only a young lad but we have known of him for a long time. 'We tried to get him here some years ago but he signed for DC United and that stopped the progress of us keeping tabs on him.' United had previously denied any interest in the American star, who has been a considered a massive prospect ever since Inter Milan offered a six-figures fee for him having watched him in just one junior tournament prior to his 14th birthday.

United beat Blackburn Rovers by 1-0 today to stay top of the Premiership. Chelsea remain second.
