Mazzarri was asked if an era was over at Napoli, but he resisted this suggestion.
"I don't know what that can mean. I always say the same things and nobody listens to me. It is an ugly defeat, but these lads have given their all for three years and it can happen to go through a period of fatigue after reaching the Coppa Italia Final and a great Champions League run. The process of growth comes through this too.
"We are in the Europa League for next season. If we invest in youth then we have to give them time, as we can't get everything straight away like Milan and Juventus. We are on track for what we set out to do in the summer. In fact, we could've been even lower down the standings considering how this season has gone."
