It's just incredibly unlucky for Nani that Arbeloa was closing him down like that in that moment. Zidane used to do that jumping studs up control of the ball constantly, almost every game. It is one of my enduring memories of him, and Henry used to do it a fair bit. The only way tonight's situation was any different was that there happened to be a player there as Nani went up to control it.
It's at an awkward height for Nani, he couldn't really head it in that situation, and I suppose he could have let it come down further, but I don't blame him for trying to control that, I'm sure there are plenty of players who would have done the same thing. Also, referees cause problems with their inconsistency. In the WC final between Holland and Spain, Nigel de Jong did a worse version of what Nani did tonight and Howard Webb didn't even book him. Tonight, Nani does something not as bad and gets sent off. Refs cause themselves problems by not consistently applying the laws of the game.
I'm glad Fergie hasn't come out and spoken to the press, he's obviously too annoyed to be able to talk to them and I'm sure he'd only get himself in trouble. Also, has anyone heard that Bale was spotted at the game? I'm guessing that was to see his future employers (Real) play?!
