United Eye Up Sporting Lisbon`s Nani

Manchester United swooped to take Cristiano Ronaldo from the same club for £12.25million in 2003.

And now Sir Alex Ferguson's assistant Carlos Queiroz has identified the 19-year-old Nani as another potential Old Trafford star of the future.

The right-sided midfield player was a key figure in Sporting's second-place finish in the league last season and has already netted three times in six games this term.

He is contracted to the Lisbon outfit until 2008 and his club want to extend it by two or three years, while also eager to insert a clause stating that he cannot be sold for less than £17.5million during that period.

Word is though he definitely isn`t for sale.
