Refereeing a game of this magnitude is their pinnacle, their one shot at being the centre stage. So they take it by making themselves the main talking point.
Names like Ovrebo are only remmebered for their terrible refereeing performance.
Guys like Collina, who got to manage games such as Juve/Milan and the Rome and Milan derbies, they did not need to make themselves a name for themselves, they already had one.
Feel sorry for City, and not so. Really wanted Arsenal to win though as I feel we can beat them more likely than we could Bayern.
