Chelsea defender Kalidou Koulibaly says he was prepared for Thomas Tuchel's sacking.

Having seen Tuchel replaced by Graham Potter in the dugout, Koulibaly now knows why he was told to expect a rollercoaster time at Stamford Bridge.

“This is the beauty of football," he told Il Corriere dello Sport. “I arrive with a coach who wanted me at all costs, and then he leaves.

“Both Tuchel and Potter play with the three-man defences, I was used to a four with Napoli.

“It's another string to my bow, you never stop learning. I knew I was going to have a hard time, and that's proved true. Even Zola and Drogba had anticipated that for me."
