The 21-year-old centre-back has been one of the beneficiaries of Frank Lampard being named as Blues manager at the start of the season.
He was with Lampard on loan at Derby last season and was named their player of the year, ahead of team-mate Mason Mount.
And after his performances this campaign, a tweet from seven years ago surfaced that showed just how much being a Chelsea player means to him.
He wrote: “Been at Chelsea since I was 8. Now I am 14, 6 years and this is just the beginning. Dream; Believe; Achieve.”
There are certainly comparisons that can be drawn with John Terry, who made his Chelsea debut 20 years ago this week.
He has already established himself as a first-team regular at the Blues and is set for his 12th appearance of the season against Watford on Saturday, which is live on talkSPORT.
Tomori is different and here at talkSPORT.com we have taken a look at what sets him apart from the rest.
He’s always been underestimated
The defender was born in Calgary, Canada, and is also eligible to play for Nigeria through his parents but has committed to play for England.
Tomori went completely under the radar with our national coaches and was actually playing for Canada’s Under-20s against England when they were alerted to his talent.
