Man, Uruguay and Suárez were playing really well and deserved to win even before Marchisio's red card (which is questionable imo, simply because slow-mo completely distorts the image), but he did again something he hadn't done in a long while, being an irresponsible ass. I love how he plays, but that really doesn't help his team, and if he'd been sent out nobody could've complained. I expect him to miss the round of 16 game at the very least, assuming Busacca or whoever is in charge of sanctions grows some balls.
Overall Uruguay played better, I'd really liked Italy against England and in previous games, not sure what changed in the last two. Against Costa Rica Pirlo was the only one playing, and today not even that, sadly.
I just hope the Uruguay victory isn't really demeaned because of Luis when they clearly dominated, but then again, people always use the last images to form their impressions of the game so it wouldn't be unexpected if everyone hated Uruguay from now on.
