Cristiano Ronaldo claims poor refereeing decisions denied Manchester United the chance to take more than a slender 1-0 lead to Arsenal in next week's Champions League showdown.
Ronaldo claimed Danish referee Claus Bo Larsen "did not have best night" and two crucial offside calls denied United goals. TV replays showed Brazilian midfielder Anderson was onside when he was flagged, while Ryan Giggs, who went on to score, was a borderline decision.
Ronaldo said: "Two offsides are not offside and a few fouls he didn't give. It was not his best game."
He added: "The first one Anderson was not offside and, with Giggsy, I'm not sure either. They are not great decisions but you have to respect the referees even if they were not brilliant - and just hope they will be better at Arsenal."
Ronaldo insisted United deserve to be the bookies' favourites to hold on to their European crown and believes they will triumph in next week's semi-final, second leg at the Emirates.
"We should be the favourites, we are the holders of the Champions League and we are full of confidence," said the Portugal winger.
"It's going to be more difficult now Arsenal are at home but it's no problem to us as we are very experienced.
"We created so many chances that I believe we will score again at Arsenal next week.
"It was [Manuel] Almunia's night and he stopped a few goals and, when the goalkeeper is the best player on the pitch, it shows how difficult it is for other teams to play against us."
