Napoli midfielder Fabian Ruiz insists they're capable of "hurting" AC Milan.

The two high flyers meet on Sunday.

“Milan are in great shape right now and if they are top of the table, it's because they are doing well," the Spanish midfielder told Sky Sport Italia.

“They are unbeaten in 19 Serie A games and that says so much about how well they are working. It's a very difficult match for us, but also a very important one. We are working on ways to hurt Milan and bring the three points home."

He added: “You never know, anything can happen in football. We have a strong squad, are focused and if we continue like this, we can be up there at the end of the season.

“Everyone asks me about Gattuso, whether he's always angry or shouting, and I can only say good things. He's a real man, he thinks only of us and if there's a difficult moment, he is right by your side. He's both a coach and a friend to his players."
