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.
"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."
