AC Milan coach Max Allegri hinted his players didn't work for eachother after their shock defeat to minnows Cesena.
The Rossoneri gave Zlatan Ibrahimovic his debut, but were beaten 2-0 by the minnows who were playing their first Serie A home game in 19 years.
"It's difficult to find positives from this game. We hadn't started too badly, but we knew Cesena were strong on the counter," said Allegri.
"The second goal was the real blow, as to concede like that on the counter-attack from our own set play was disappointing.
"We weren't organised enough and didn't move the ball around cleanly, wandering around the field without a specific plan in mind.
"I tried the new players who just arrived, but that's no excuse. We were simply lacking in grit. This system requires everyone to work for everyone else, it's something I've been trying to tell the team since the day I took over at Milan."
