AC Milan goalkeeper Pepe Reina has paid tribute to Chelsea boss Maurizio Sarri.

Reina played for Sarri at Napoli.

“I really enjoyed playing under Sarri," Reina, who worked under the 60-year-old at Napoli, told The Independent.

“I consider myself good at it [playing the ball out as a goalkeeper to build the play]. It depends on the philosophy of the manager and the team.

“Sarri uses it more than others because he likes to be able to exploit a good goalkeeper who has feet like that.

“At some point, it [Sarriball] came natural to us, we played this way even blind. He just wants you to be brave on the ball and eventually it came natural.

“It's all about executing: every League requires a different approach and in England the rhythm is different. In Italy they are tactically better and stronger, better positioned.

“Sarri is a very complete manager. He is so cynical with every detail, every detail counts.

“It's not just that [focusing on playing Sarriball]. It can turn you crazy because he likes to think about football 24 hours per day."
