Inter Milan boss Jose Mourinho says Manchester United escaped with a 0-0 draw last night - thanks to Spanish ref Luis Medina Cantalejo.
"If we go there and if we have a referee who gives so much protection to the away team, then we go to the quarter-final," he said.
"The referee did not please me in the slightest, but I don't want to talk about details.
"But if we can have a referee like this at Old Trafford, it would be fantastic."
