New Chelsea FC manager Frank Lampard says that Callum Hudson-Odoi is not guaranteed game time at the English giants.
The retired midfielder has made it clear that the highly-rated attacker will have to work hard for his place in the Blues starting line-up.
Hudson-Odoi, whose current contract with Chelsea will expire in June 2020, has been linked with German Bundesliga giants Bayern Munich.
"I am not going to say things that are pie in the sky but, with his talent, he can be central to this team, he can be central to England," Lampard told BBC.
"He can show, right here at Chelsea, the team he came through the academy at, that he is going to be a world-class player - because I truly believe that.

"I will pay a lot of care and attention to Callum - because of the contractual position he is in - to try to get him to stay, and not with any lies or any false statements to him.
"That, of course, goes to a decision between him and the club and I am not involved in the financial negotiations, but I can certainly tell him how I see it and I see him being a huge player for us."
Formal contract negotiations are yet to begin between Hudson-Odoi,18, and Chelsea according to BBC.
However, a five-year deal worth over £100,000 ($125,000) a week is on the table.
