Manchester United are interested in the Spanish whizkid Joan Sastre.

United are being linked with a move for the Real Mallorca youngster, who is also on the radar of Real Madrid and Barcelona.

The 21-year-old right back is seen as a top prospect in Spain. He was very impressive as Mallorca got promotion to the Spanish second division last season.

Sport claim that Sastre is being watched by scouts from Real and Barca, along with Villarreal.

United are also taking an interest in the player. They would place him in the U23 squad should a transfer go through this summer.
