Chelsea signed Kalidou Koulibaly as a top-class signing from Napoli. The experienced Senegal international was expected to replace Antonio Rudiger in the left centre-back position.

However, Koulibaly struggled in his debut season at Chelsea. The former Napoli captain was sent off against Leeds, in his third game for Chelsea, where be put in a very horrible performance.

Todd Boehly has revealed what Koulibaly told him after he signed up for Chelsea.

“There’s no bigger sport in the world,” Boehly said.

“When you think about just the size and scale of European football, it’s just mind-numbing and there’s no better league in the world in the Premier League.

“If you look at how these guys play, the speed with which they play the game. One of my players who I had a great relationship with is Kalidou Koulibaly.

“Koulibaly came over from Serie A (where he played for Napoli) and he told me one time, ‘In Serie A, I get to think and then run but in the Premier League, I have to run while I think, and I’m still adjusting to that’.”

Chelsea under Todd Boehly have spent  massive fees on a host of new defenders, including the likes of Benoit Badiashile, Axel Disasi and Wesley Fofana.

The Blues are expected to sign a top centre-back this summer, to replace the outgoing Thiago Silva.
