The young defender broke into the Blues team under former manager Frank Lampard last season but fell down in the pecking order at Stamford Bridge.
Last year was so frustrating for
as he suddenly lost his place in the squad and only made two Premier League appearances.
As a result, Tomori was allowed to leave Chelsea forAC Milan
- albeit on loan in order to get regular first-team minutes for the remainder of the season.
“I was suddenly out of the squad and I don’t really know why,”
Tomori explained to theTelegraph
“I just thought I needed to work hard. Then I went to speak to the manager and he said you’ve just got to train harder, so I took that on the chin and thought that’s what I had to do.
“Mentally, it was difficult because you just want to be playing and on the pitch, and feel part of the team. And it was difficult for me because I wasn’t really feeling part of the team and I was wondering what had happened.
“I was trying to do extra and push myself more but, at that time, nothing seemed to work and nothing was explained to me.
“It was so frustrating. 2020, football-wise, was very, very difficult, especially after the way 2019 had gone for me playing games. From being at 100 to literally going down to zero and then not knowing the reason why it had gone to zero, it was very challenging.”
