Chelsea boss Thomas Tuchel admits he's delighted with Timo Werner's current form.

Tuchel has challenged Werner to keep producing the kind of goalscoring form he has shown against Southampton and Real Madrid.

“Now he has made it difficult to leave him out. I'm impressed, he was very, very good in the last two games," Tuchel said.

"These were two games when he was much better than in any other game and he showed what he is capable of. Everybody thinks we as managers do the line-up, and of course we do.

“But in the end the players take care that you don't leave them out, they do it in training or in games, and of course in games it's the opportunity for everybody.

"Especially for strikers, things can be turned around in minutes, in moments, whole careers can be upside down and in any direction but always as a striker you can have a chance to put things into your favour, as a substitute or if you have the chance to perform from the beginning. He did in the last two games and that's what we want from him. It's what he needs to show and then he takes care that he plays.
