Chelsea defender Kalidou Koulibaly says he'll be thrilled if former club Napoli win the Scudetto this season.

Koulibaly left the Serie A leaders for Chelsea last summer.

He said, "If this Napoli is stronger than that of (Maurizio) Sarri who touched the Scudetto? If they win we will say that they are stronger.

"It was a different football, we cannot make comparisons. That Napoli played in an incredible way, we dominated all the teams. Today even when cannot dominate games, they are extraordinary.

"I see them solid, compact. Will it be the Scudetto? I hope so, we will not say it out of luck, it will also be mine."
