Marek Hamsik insists Napoli are still capable of qualifying for Europe.
Napoli haven't won any of their last seven games and have slid from fourth to seventh in Serie A.
Midfielder Hamsik said: "We still believe in Europe and we want to redeem ourselves against Milan.
"We will try our best, because if we play how we know, we will be protagonists. The problem is only the goals.
"We create a lot, but we don't manage to be protagonists. We have to exploit our chances. It's the only way I know to get out of this rut."
