Napoli defender Kalidou Koulibaly admits he learned plenty during his time with Chelsea boss Maurizio Sarri.

Koulibaly also spoke of his time with Newcastle United manager Rafa Benitez and current coach Carlo Ancelotti.

“Rafa Benitez and Ancelotti have a pretty similar style of football. I was also fortunate enough to play with Sarri and his football was truly wonderful," Koulibaly told the Corriere dello Sport.

“He allowed me to see football and games in a different way. His philosophy was concentrated on tactics, it was all predicted and planned with him.

“Today, when I watch a game involving any other team, I don't see it the same way as I did four or five years ago. I owe that to Sarri.

“Benitez allowed me to discover real football. I was in the French second division, then Belgium, but he gave me the opportunity to come to Serie A for the first time, a truly important league.

“His football is very similar to that of Ancelotti, because they are Coaches who have won a great deal, worked at top clubs and their visions of the game have many crossovers.

“Everyone knows what Ancelotti has done in his career, but what surprises me the most is the humility he still has and the desire to keep winning."
