Napoli coach Rafa Benitez was far from happy with his side's display against Verona on Sunday afternoon.
An unexpected away defeat at Verona means that the Partenopei have lost the third place in the table on goal average with Lazio with a chance to open a three-point gap if they beat Torino on Monday.
"I am bitterly disappointed and angry because I don't like losing like this," Benitez said.
"We started badly, we conceded a goal and in the second half we kept making mistakes which we paid for. I clearly expected a different game.
"We had chances to change the outcome of the game but the approach just wasn't right from the beginning. It seems we lack maturity to play and win in all competitions. It just means that we have to keep working to improve.
"After three games played with great intensity against Lazio, Internazionale and Dynamo [Moscow], we struggled in the fourth one [but] I don't believe the squad is tired.
"[Rotation?] Many played a lot so we had to rotate. Keeping the same level of intensity every three days is not easy."
