He was poor in parts, but it is European football what did you expect, the referees are always officious.
I thought that he made some good decisions though. He awarded a goal kick to us correctly from a very difficult angle, he got the back pass right, despite the pressure.
Also you must take into consideration that it was in the Nou camp, with 80 odd thousand barca fans jeering whenever a tackle is made by the opposition. Although I did not think much of the crowd, compared say to a European night at Anfield. I think many of them thought the win was a guarantee.
