It was a heavy misstep for Milan, i didn't expect it. Luckily i did not bet in this game because the opposing team really was absolutely within its reach.
Their coach, Cannavaro, was good at placing the team on the pitch and he managed to win against Milan.
Now i have not followed, do Milan have any problems to pass the turn? I think not, but if someone can confirm.
Milan wasted the opportunity in their last match to advance to R16 automatically and that is very unfortunate, because in any case in the play-off round later the chance to qualify is still not guaranteed for them. Every team they will face later will definitely fight hard, this is like a life and death match. Now we see in the play-off round which team the Rossoneri will face, if you look at the draw rules they will be matched with Feyenoord or Juventus, if I'm not mistaken.
