Sporting CP are moving for Real Madrid striker Raul de Tomas.
Real have informed De Tomas he can leave this month, though participated in their preseason tour of the US.
The centre-forward was outstanding for Rayo Vallecano last season and has an offer from Real Valladolid.
However, Sporting are also keen and have asked Real about a season-long loan for De Tomas.
Last season, he scored 24 goals in 32 games for Rayo in the Segunda Division.
