Napoli winger Jose Callejon says the way they start will be crucial in tonight's Champions League qualifier at Athletic Bilbao.
Napoli go into the second-leg with the score locked at 1-1.
"We know Athletic's qualities, but we have to remember that we are Napoli and therefore we do not fear our opponents," said Callejon.
"In the first leg we didn't make the most of our scoring opportunities, so must try to do better. We are playing in a tough arena against a side we respect, but we are Napoli and we are here to win.
"Tomorrow night the first 15 minutes will be crucial, as they can dictate what path the game goes on to."
