Audio problem: During any fight when people are yelling "Mo cuishle", watch the spectators around and you'll notice that no one is mouthing the words, or is in sync with those words. Even if the yelling came from offscreen (i.e. from the farthest bleachers) the noise should have sounded from far away, not as neat and close as it sounds.
Audio problem: In the scene after the referee has shouted that it's Sudden Death, the commentators are talking. The only sound you can hear is them talking. But if you look behind them, there are loads of people who are shouting. (01:21:00)
