Napoli midfielder Walter Gargano says their clash with Juventus is a must-win game.

"We must beat them," Gargano told journalists. "We have to do it for the fans and to improve our League position.

"I'm not going to make any predictions but all I am going to say is that Juve will struggle against us.

"After all, we taught them a lesson last season and we will be spurred on by our fans.

"One thing is certain - we aren't ready to give up our unbeaten home record."
