Walter Mazzarri warns Napoli’s 3-0 defeat to PSV  shows “either we drop points in Serie A or we drop them in Europe.”
The Partenopei lacked strength in depth last season and thought they had turned that corner with reinforcements over the summer.
However, the second string side was crushed 3-0 in Eindhoven for tonight’s Europa League clash.
“We started well, but then lost the ball too many times in midfield. It is a game we have to put behind us,” the Coach told Italia 1 television.
“We have to mature and realise squad rotation is necessary for the position we are in. The fact is, there aren’t enough players to cover every competition.
“Either we drop points in Serie A or we drop them in Europa. Now we have to think ahead to Udinese this weekend.”
