Chelsea's board and staff are very worried about the fact that manager Antonio Conte is not happy with the club's record signing Alvaro Morata.

The Spanish striker joined from Real Madrid in the summer as a replacement for Diego Costa, who eventually left for Atletico Madrid.

But Morata has gone through a stop-start season in England, and he has not delivered the consistent performances and goals many were expecting.

The Sun claims that Conte is not happy with Morata's consistency, or his effort in some games.

It is unclear whether Morata will be at Chelsea beyond the summer. Everything is up in the air for now, including the manager's future.
