Chelsea midfielder Kai Havertz says he's a better player for working with manager Thomas Tuchel.

Havertz was speaking ahead of tomorrow's Champions League clash at Lille.

He said: “The arrival of Thomas Tuchel was good for us. We won some titles and me personally, I think I've grown as a player.

"As a player, there will be negative moments and I've had this in the last two years as well. Personally, I think I've grown from these situations where you don't have a good moment. I am young and I can learn a lot.

"A career doesn't always go up and up. Sometimes you fall down a bit, sit on the bench and learn from it. People don't always see that it helps me."
