The Partenopei beat Villarreal 2-0 in their first Champions League/European Cup home game for 21 years.
"This time we didn't throw the lead away. The watchword was always play as if it's 0-0," the Coach told Mediaset Premium.
"We've got to play one game at a time. The lads were shattered in the second half. Unfortunately, we've lost Salvatore Aronica too. Last season the injuries were not so frequent."
"There is a lot of work and we've grown earlier than expected. Mentality is everything and I always told the lads not to think about the opponents, whether home or away. I think they followed my orders to the letter.
"Aside from what the results may be, Napoli are always in the game. We'll rarely fall without a fight. At times, such as the last two Serie A rounds, we were unable to win, but were always organised. That will be the case all the way."
