Both teams are strong and play disciplined in defense. It will take a magic moment or a big defensive mistake for a goal to be scored.
Btw, do you guys find Vieira's fouls annoying? I find them annoying because they're too "smart fouls".

He was doing the same when he was in Arsenal and Juve and it made the opposition fans go mad. He almost always fouls just enough to stop a potential danger but also, enough not to get a yellow. Soft fouls, in the center of the pitch. The refs can't give him yellow for such fouls because if they do, they will have to give a yellow for every single foul. But those fouls are enough to stop a counter and to give time to his defense to organize.
