Napoli have impressed many European onlookers this season and they are keen to make a point tomorrow night as well.
Mazzarri said: "It's pleasing that people are starting to take notice of our potential," Mazzarri added. "First in England, now in Germany."
The Stadio San Paolo outfit do go into the game following defeat at the weekend though, a shock 2-1 reverse at home to Parma.
"When Napoli have fallen in the past, we've always put on a great display in the following game," the Coach responded.
"We did well towards the end of matches last season and this hasn't happened this time around. Actually, we are now losing games at the death.
"The side has never given up though and they've always played some excellent football, even if we have made some mistakes.
"We correct every error though and we always look to improve on a mental scale."
