Chelsea boss Maurizio Sarri ha revealed that putting too much pressure on Ghanaian youngster Callum Hudson-Odoi could be dangerous for his progression at the club.
The 18-year-old climbed from the bench to score for the Blues in their 3-0 win over Dynamo Kiev in the Europa League last-16 first-leg tie at Stamford Bridge on Thursday night.
Hudson-Odoi put up an incredible performance impressed in pre-season under Sarri but has found regular first-team opportunities few and far between this season and was subject of serious transfer interest from Bayern Munich in the January transfer window.
When asked if Hudson-Odoi can fulfill his promise at Chelsea, Sarri said: "I am convinced, he doesn't have to do anything to convince me. He is a very good player. He needs to improve. At 18 he can't be at the top.
"He will be ready to be at the top at 22 or 23 years. We need to improve without the media of the pressure of the media, fans the club. His training is really very good.
"When you have pressure when you are 18 it is dangerous, you can lose the target. The target is to improve. So it is dangerous. This is why I don't like to speak about him."
The highly-rated youngster was close to leaving Chelsea in the January transfer window but the club rejected a transfer request from him.
