Champions League referee admits mistake Bazza, surely you're not going to continue arguing this point after the President of FIFA AND the referee in question have both said he made the wrong call.
If the advantage had have been played and Giuly missed, he would have been slated, not the ref, I firmly believe the referee would have been given a lot of credit to try and maintain the flow of the game.
And to elaborate on what EC said previously about discrecion within the game and the ref being right either way - perfectly put - its knows as FIFA Law 13 - the commonsense rule.
FIFA did make a bad call having a referee from Norway, they have a weak domestic league and obviously their officials are not up to officiating elite-level matches such as the Champions League final - I think there were much better alternatives around than that crew!! One of the linesmen posed in a Barca jersey for a newspaper a few days before the match for heavens sake!!
"Professionalism" - this is the Champions League Final don't forget!! 
PS: Terje Hauge has refereed nine (9) top-level matches this season (05/06) and in those nine games he has issued a staggering 31 yellow cards and two red cards!!
