Napoli winger Jose Callejon says they won't give up on reigning in Serie A leaders Juventus.

Juve are now 15 points clear at the top of the table.

But Callejon says: “Juve are a very strong team.

“They have been for years and with Cristiano Ronaldo, they've improved even more. But we're a great team too, we do our jobs and we fought them in our two League games.

“Unfortunately they didn't go well, but we've always been in second place: it's not over yet, we mustn't give up on anything and we must keep going to the end."
