Inter Milan coach Walter Mazzarri expects former club Napoli to remain competitive next season.

Mazzarri believes they will remain competitive with Rafa Benitez now in charge.

"They came second last season after four years of growth and I think they can only improve," Mazzarri said.

"As a club they're in good shape and there's every chance of them succeeding. But Napoli is the past for me - I want to talk about Inter now."
