AC Milan hero Billy Costacurta defended coach Stefanp Pioli after defeat at home to Udinese.

Milan lost 1-0 on Saturday and were booed off the pitch by the home fans.

"This was a flat performance," Costacurta told Sky Italia after the game.

“Milan were good for 30 minutes against Juventus. PSG are a strong side, so it's acceptable to lose against them. In Naples, they did well in the first half and even later, but this defeat is worrying because they have nothing in attack.

“Only Rafael Leao invents something once in a while. Giroud scored two goals in Naples, but the most alarming thing is when they need something from other players.

“I don't know this environment. I came through tough times when the coach took responsibility and I think Stefano is doing so.

“What I think, however, is that Stefano has fewer responsibilities than his players."
