Nani gloat from Sporting

Sporting Lisbon have warned Barclays Premiership clubs that it will cost £13.5million to sign winger Nani.

The 20-year-old has been attracting interest this season following his displays in the Champions League, with Tottenham the latest club linked with a move for the Portugal international.

A Sporting spokesman told skysports.com: "The club that wants the kid have a price, 20million (£13.5million). Only by this money would we be disposed to let Nani leave."

The spokesman added: "We know of the interest of several English clubs for Nani, and that is normal because of his quality - but until this moment we have received no offer in writing."

Nani has been compared with Manchester United winger Cristiano Ronaldo, who was signed from Sporting in 2003.

United have been linked with a move for the Portuguese prospect following their previous business with the club. French side Lyon have also been suggested as a possible destination.

Nani is represented by Jorge Mendes, who is also the agent of Chelsea boss Jose Mourinho.

"The decision depends on Sporting because the player has a deal," said Mendes. "But Nani is a player of enormous potential and other big clubs have asked about his situation."
