Inter Milan coach Walter Mazzarri is expecting big things from Mateo Kovacic.

Mazzarri has likened the youngster to Napoli ace Marek Hamsik.

"Marek is a top player who works hard both in defence and attack," said Mazzarri.

"Mateo has similar potential and I hope that if we can make the right adjustments - for example when attacking and getting shots in on goal - he can become very similar to Marek."
