The 19-year-old was given his first-team debut by Frank Lampard last year and has made one substitute appearance in the FA Cup against Barnsley since Tuchel arrived at the club in January.
Anjorin has been training with Chelsea’s first team and could be included in the squad for their FA Cup quarter-final with Sheffield United this Sunday.
Anjorin could have potentially left Chelsea on loan in the January window in order to get more playing time.
But Tuchel is happy that the forward has remained at Stamford Bridge to continue his development.
‘I got to know him here. From the first day I was very impressed because he’s a very physical player, tall guy, strong guy,’ Tuchel said on Friday.
‘He has the ability to keep the ball under pressure because he has the body for it.
‘He has the physical ability to play and train with us on this level. He had some minutes against Barnsley in the cup game we tried to involve him now in the group against Sheffield United because he trains very well, we decided to keep him to get to know him better not to give him on loan or find another solution for him in winter and I’m happy about that.
‘He is very strong in finishing in our training a very nice character a nice guy from the academy, very humble and at the same time totally focused, totally clear when you talk to him very self-aware a pleasure to work with him and I hope he continues like this.
‘He needs to be patient and impatient at the same time which is always a task for the young guys at a big club.’
