Chelsea's would have been a penalty... IF he hadn't dived first.
It was the equivalent of missing an open goal from a yard out, we were lucky that the player was stupid enough to dive when he didn't need to, and lucky that the ref spotted it. (Although I wouldn't be surprised if the ref thought he was evening things up.) In any case, the correct decision was made.
Mourinho's rant was nothing more than a desperate attempt to shift focus and blame away from himself. Normally when he starts going off like that, it's to draw the focus to himself and take the pressure off the players, but here he was shifting some of the blame onto the players themselves, as well as the referee. Unless Chelsea can suddenly turn it around and go on a winning streak to drag themselves back into the top four race, I think he'll either walk or be pushed before Christmas.
