Sporting CP have referred interested clubs to Rafael Leao's buyout clause in recent days.

The exciting teenage talent has been likened to Real Madrid star Cristiano Ronaldo and Valencia's Nani, who both came through the same Sporting youth system.

O Jogo says Manchester United are in contact with Sporting about Leao, but are not alone with PSG and Red Bull Salzburg also keen.

Sporting are desperate not to lose Leao over the summer and have added him to Jorge Jesus' senior squad this season.

Leao penned terms to 2022 recently, with his contract carrying a buyout clause of €45m.
