In the 7th minute Swiss referee Massimo Busacca had to warn PSV defender Alex who clearly couldn't handle Liverpool forward Bellamy. It was a penalty waiting to happen, and a promise of an interesting Champions League match. But not so, after the 7th minute absolutely nothing happened.
An easy night for a referee when one team (Liverpool)can live with a draw and the other just isn't up to scoring. Somewhere in the second half Busacca saw a foul, but it rather looked like he was testing his whistle: yes, see, it still works. Busacca, who this year at home showed 15 yellow card in two matches, could have stayed at home. And so could the audience.
