Milan coach Massimiliano Allegri expects Catania to be no pushovers in Saturday night's clash in Sicily.
The Rossoneri are hoping to maintain the pace following a good week which saw them through to the Coppa Italia semi-finals.
Allegri is hoping to force stays with his players, but warned against Catania resistance.
"It will be a stressful game for us tomorrow. They come off the back of negative results, and so they will be motivated against us," Allegri told the press.
"They are pratically an Argentinean team and so we need to be careful for all 90 minutes.
"We have to be very good though and just think about playing."
Allegri confirmed both Zlatan Ibrahimovic and Antonio Cassano will be starting against the Etnei.
"Cassano is working very well. If all my players played like this it would be good for Milan," he said.
"Ibrahimovic? He rested on Wednesday, and so tomorrow he will play."
