Napoli coach Walter Mazzarri admits their heavy schedule is wearing on his players.

The Azzurri face Juventus tonight at the San Paolo.

"For us this is our fourth consecutive game played within two days of the previous one," said Mazzarri.

"We got back from Bergamo at two o'clock in the morning on Sunday and yesterday we were back on the training field.
