Napoli coach Walter Mazzarri admits he's frustrated he won't be on the bench for their Champions League clash with Chelsea.

Mazzarri will not be on the bench due to a two-game touchline ban after he pushed Nilmar for timewasting during the 2-0 win over Villarreal.

"I always want to give all of myself to the team, so this is why I don't like being away from them. I was not the one who behaved in an unsporting manner - it was Nilmar."
