Rizzoli knows his prima donnas, he ignored Kaka for most of the match for instance, he ignored many little fouls for the sake of the match and he ignored most complaints and angry gestures.
Maybe all that lgnoring caused the ruckus at the end of the match, maybe the players were just tired.
Maybe also Rizzoli is a little too close to the action. He has the knack to let the ball go between his legs or to take a step to the side, but he really doesn't have to be that close.
Not a bad match at all. You could see the lesser team had a better coach, and the Lyon players really gave it all.
