Napoli coach Gennaro Gattuso is demanding better from his players after their 6-0 rout of Genoa.

Chucky Lozano struck twice, with Dries Mertens and Piotr Zielinski also among the goalscorers.

“This result is very harsh and does not reflect the game," insisted Gattuso on Sky Sport Italia.

“If Piotr Zielinski hadn't scored 30 seconds after the restart, it would've been a very different match. We have to focus on improving and finding the right balance, because we need balance in order to play this type of football.

“I am not giving Lozano any leeway, so he is a different player now. When he arrived, he was not at 100 per cent mentally or physically. He would kick the ball and fall over like a child, now he has strength in his legs.

“I knew Lozano from his days at PSV, he always attacked down the wing, but last season he wasn't at his best at all. He's playing now because he's in good shape.

“The whole team hit rock bottom last year and we still need to be consistent over 90 minutes."
