It was only a few months ago that Hudson-Odoi was determined to leave Chelsea.
Bayern Munich were interested in the player. Now he has renewed with the Blues for another five years.
And Granovskaia had some very positive things to say about Hudson-Odoi.
She said to the club's official website: "The club has already been rewarded this season by some brilliant performances from our young Academy graduates, and Callum's new contract guarantees Frank has another outstanding prospect at his disposal.
"I have seen Callum come through and he's a fantastic talent,' said Lampard. 'He is going to be central for us on the pitch and that is the opportunity in front of him now.
"There are things as a young player that he will want to improve but he can be central to this team and for England. I want to work with him, I want to drive him forward and I want to improve him as a player.
"Callum can show, right here at Chelsea, the club he came through the Academy at, that he is going to be a world-class player because I truly believe that."
