Catania striker Giuseppe Mascara rubbished the quality of AC Milan's victory on Sunday.
The Rossoneri managed to snatch the three points thanks to two late goals from Klaas-Jan Huntelaar.
"It makes me really angry to lose the way we did," revealed the Etnei striker. "In the second half we played really, really well. For a long spell Milan were on the back foot.
"If we had won a point on the night we would have been really happy and it would have helped our morale.
"But now we find ourselves in a complicated situation and we cannot afford to make errors in the next games."
