Napoli coach Walter Mazzarri was left disappointed with their 2-2 draw against Catania.

The Azzurri coughed up a 2-0 lead to be pegged back by the Sicilians.

"This match is part of our maturation process and we cannot throw away a 2-0 lead this way," said the Coach.

"We hardly ever suffered at the back and could've gone 3-0 up, but were too sluggish in our finishing.

"It's not possible to let in the same corners that knocked us out of the Champions League. We can't keep conceding the same goals. All sides have strengths and weaknesses. We made a few changes when marking from set plays, but we're still getting it wrong.

"It's such a shame to throw away three points in this way. We did something more and knew we were tired, so Catania worked out they should leave it late to pile on pressure. They also copied our tactics, so until there was a breakthrough it was difficult to find space.

"We really shouldn't have let ourselves get pegged back that way, especially after we introduced an extra midfielder. Maybe we are naïve, as we underestimate the danger from corners late on. We've got to man-mark and put an end to this weakness."
