Sporting Lisbon are reportedly aiming to offload William Carvalho this summer.
The Portuguese outfit are keen to cash in on the midfielder before his contract expires, according to Sky Sports News.
Carvalho is said to be eager to play in the Premier League, and Everton have been touted as the favourites to sign the Portugal international.
New Toffees manager Marco Silva has worked with the midfielder in the past, having coached him during his time at the helm of Sporting.
Carvalho has been named in the Portugal squad for the World Cup finals.
