The agent of Sporting Lisbon winger Carlos Mane admits interest is growing in the teen. The Daily Express says United are leading the Premier League race to sign Mane, with Liverpool, Chelsea, Manchester City and Tottenham also keeping tabs on the highly-rated winger.

"Carlos is concentrating on maintaining a place in the Sporting first team," Dan Law said.

"2014 has started really well for him, and he has scored three goals so far, but we should not forget he has yet to make more than ten first-team appearances.

"He also enjoys a long-term contract at Sporting, they value him highly and so it is premature to be talking of a move.

"That said, I am aware of a number of clubs with real interest and who are keeping tabs on him, and it has to be said that whilst a move to the Premier League is the ultimate goal for Carlos at some point in the future - just one reason being that he has family in the UK already - some Bundesliga and Serie A clubs might appear to be more advanced in their interest at this stage."
