Napoli coach Walter Mazzarri is wary of a wounded Inter Milan tonight.

Inter have collected just one point from the last five Serie A games.

"Inter are a quality team and have the raging strength that comes from a wounded side. Recently nothing has gone right for them and I would hate for the tide to turn against us, just as we turned against Chievo.

"This match can be a classic trap for Napoli. We've got to be 100 per cent concentrated, paying attention to every detail and not letting anything go. Every ball we lose could be the one that decides a victory or a defeat. If we play the way we have done in recent games, then we can do this," said Mazzarri.
