Maurizio Sarri has called for Callum Hudson-Odoi to show some respect to Chelsea after confirming the wantaway forward was blocked from leaving Stamford Bridge in the just ended transfer window.

Hudson-Odoi, 18, handed in a transfer request last week in an attempt to force through a move to Bayern Munich.

He said: “Callum is 18. He has to respect the club, the academy, everything.

“If you are one of the best young players in Europe, maybe the academy helped you.

“So you have to respect this. He is improving on the pitch and he is the future of our club and the future of English football.

“He’s a great player. He will become one of the best in Europe also in another team, but he has to respect the work of the academy coaches.”

He continued: “Here, it’s his home. We will be patient with him because he’s a boy from the academy.

“I don’t know if, at another club, people would be patient with him after five or six matches.

“It is very difficult to go to another country and adapt or play very well immediately. It is better for him to try and improve here.”

The forward has been at the club since the age of 8.
