United managed a 1-0 win at Old Trafford on Wednesday and will face Arsenal on Tuesday at the Emirates Stadium.
“We should be the favourites, we are the holders of the Champions League and we are full of confidence,” he said.
“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.”
