Former Italy star Antonio Cassano believes Juventus have problems between Cristiano Ronaldo and coach Maurizio Sarri.

Cassano reckons Juve are hiding an issue between the pair.

“I think Ronaldo has a big problem with Sarri," Cassano told Tiki Taka.

“Everything started with the two consecutive substitutions, which would irritate any player.

“In my opinion, there's a problem between them and Juventus have succeeded in playing it down."

Cassano also argues that Gigi Buffon is a better keeper than Wojciech Szczesny.

"Buffon should play because he remains a better option than Szczesny.

“He was always benched at Arsenal and was a backup to [Manuel] Almunia and [Lukasz] Fabianski. At Roma he had a good year, while now he is in his first year as a starter.

“Anyway, right before Gigi's mistake (against Sassuolo), it needs to be said that [Matthijs] De Ligt made yet another mistake."
