Callum Wilson in talks to leave West Ham after five months as Nuno problems mount

• Striker understood to be dissatisfied with life under Nuno

• West Ham have signed Pablo Felipe and Taty Castellanos

Callum Wilson is in talks to leave West Ham five months after joining. It is understood the striker has grown dissatisfied with life under Nuno Espírito Santo and wants a new challenge.

Wilson was signed on a cheap incentivised one-year deal and his situation is an apparent sign of wider discontent within the squad over their manager. Nuno, whose side are at increasing risk of relegation from the Premier League, is in danger of losing the dressing room’s support because of concerns over his tactics and man-management.
