Chelsea were down 1-0 to West Ham at home in Saturday’s London derby game at Stamford Bridge.
Thomas Tuchel decided to bring on Ben Chilwell for Marc Cucurella in the 71st minute, and the England international changed the game for Chelsea.
Chilwell scored the equaliser five minutes after coming on, and sealed the winner with his assist for Kai Havertz in the 88th minute.
Speaking after game, Thomas Tuchel hailed Chilwell, but also admitted that he’s yet to get his perfect rhythm.
“I think he has the full fitness you can have from training and pre-season matches. Of course you can also feel fitter and be fitter with consecutive matches in the Premier League.
“In my opinion he lacks the rhythm and he lacks a good feeling for the game. This is what I see in training. The player always thinks he’s ready, I think there are still a few things missing.
“He started for us at Everton, he came on against Southampton, he came on today and had a huge impact. This is what we want from him.
“The wing-back position is his best position in my opinion. He gives a lot of energy, runs and deliveries. So I’m very happy because these things happen like nothing else.
“Much more important than any training or talk with me is that he feels it and he experiences being back on the pitch and being decisive.”
