Chelsea centre-back Kalidou Koulibaly has admitted he hasn’t played his best football since joining Chelsea but admits he’s getting there gradually.

“I know I’m not at 100% yet, but think I’m coming to my level,” Koulibaly told The Times.

“Chelsea made a big decision to sign me and there’s a big desire in me to give back. I want to be part of this club for many years.

“This is not the year Chelsea were expecting, but sometimes when you have big changes, new proprietors, and half the team is new, everybody has to adapt. But we know how big the ambition is here and we’re going to work to win back the confidence of the supporters.”
