Napoli coach Walter Mazzarri has hit out at Inter Milan counterpart Jose Mourinho.

Mazzarri was the subject of Mou's latest sniping comment earlier this week:

"It makes me laugh when I here some Presidents compare me with their Coaches who haven't won anything other than a Tuscan Cup or a Reggio Calabria Cup."

The reference was clearly to Napoli President Aurelio De Laurentiis and Mazzarri.

"Anyone with intellect can understand that any phrase from that man does not warrant a response," replied Mazzarri.

He faces a more important test, as Napoli's result against Sampdoria will effectively decide who goes into the Champions League.

"Since I arrived here, we have earned four more points than the Blucerchiati. Without the slip-ups against Parma and Cagliari, we would've been here challenging for fourth place too.

"I am someone who is never happy, so I always want my players to give their best. Of course we can be motivated, especially in an arena like Marassi. Sampdoria know that well."
