Chelsea boss Thomas Tuchel praised matchwinner Ben Chilwell for their win at Brentford.
Chilwell scored the only goal of the game.
Tuchel said,"I'm very happy but it was necessary.
"We need everybody and we need of course a player like him in his top shape, but you cannot force things.
"I was very honest, I felt him a little bit tired, I felt him mentally a bit drained and it needed time. So now he got his chance against Southampton and took it and he was able to score and play for England which gave him another lot of confidence and today he was strong again.
"I see him in good shape and it's also necessary, we need him in this shape, we need everybody. We have many games in many competitions to play and I'm happy and of course this run of goals gives him a lot of confidence."
