FIFA, UEFA and the football journalists seem to like this kind of bland, generic referee. Kassai is there but he also isn't.
And there were a few things:
Kassai allows handling of the ball as long as it is in the middle of the field. I'm sure he noticed it, he just ignores it. I don't mind that at all.
Van Bommel, how many times have we seen him falling over after he jumped in front of his opponent? A trick he used often enough to have it named after him from now on. Kassai fell for it.
Then Antonini crashed into the goalie and got booked. It was the goalie who had his knees in Antonini's body.
The penalty was deserved, Ibrahimovic was pulled down. But a minute or so later the same happened to Arsenal's Van Persie: he got pulled down in the penalty area. This time however the attack wasn't going anywhere, Van Persie was just trying to keep the ball. But he was pulled down nonetheless.
The second goal started with an off-side.
(and then maybe not, I saw it only once, if you guys say it wasn't then it wasn't)
Arsenal seem to lack ambition. There was no power, no will to win and they wore the ugliest kit I've seen in years.
