Former Chelsea and Napoli star Samuele Dalla Bona has questioned whether Maurizio Sarri can be successful in England.

The 60-year-old Italian, who is heavily favoured to take over from Antonio Conte at Stamford Bridge, was unable to win any trophies with Gli Azzurri

"[Sarri] played great football all of the time," Dalla Bona told Goal. "[Napoli] had a good system but Juventus were able to play a worse style but still win every year.

"I think Sarri needs to make that last step to be a champion and a top coach. He is a great coach but he is not a world class-coach because he hasn't won anything – that means he isn't at the top.

"I like to see a good style of football but in the end, if you don't win but play good football, it doesn't mean a lot. Juventus don't play good but win all the time. I knew when Conte was going to Chelsea. I was sure that Conte is a winner and, in fact, he has won two titles and proved it already: the league and FA Cup."
