He only wanted to say that his family supported Josť Fonseca, the portuguese referee of the game. Then, the security entered the field, out of their natural habitat, the four black dressed in black started beating the man in white. All of a sudden, blues, reds, greens joined the guy in white, and the situation turned out black. For 10 minutes, the securities had the reversal of the coin. Good judgement was made by some fans and the quick response of the players to minimize the problem. This security was unconscient for a few minutes, and then walked out on his own feet with some help. (irrelevant stuff) There were no detentions, but there was a celebration of Benfica fans and a hospital visit by the 4 securities.
@G13: It wasnt only in Australia. It happens all over the world. If you were from another nationality you would probably think the same way.
