Inter Milan boss Walter Mazzarri is pleased with the form of Mateo Kovacic.

The young midfielder again impressed in their 0-0 draw with Napoli.

"I am a Coach who tries to improve his players. He had a few naive moments at the end tonight, but overall he is improving and is doing beautiful moves that help the team rather than just entertaining for the sake of it.

"He's doing better off the ball too now and is growing to become a champion in future."
