Real Madrid are tracking Sporting Lisbon midfielder William Carvalho.

A Bola says Real had scouts posted to see Carvalho in action against Gil Vicente on the weekend.

Carvalho counts Jorge Mendes as his agent and the Portuguese powerbroker enjoys close ties with Real, where he takes care of the likes of Cristiano Ronaldo and Fabio Coentrao.

Carvalho penned a new deal with Sporting in October through to 2018, which carries a €45 million buyout clause.
