The Inter coach was furious at Luis Medina Cantalejo's performance and accused him of favouring United.

However, a UEFA spokesman told PA Sport: "There will be no action taken."

It means Mourinho will not have a touchline ban for the second leg at Old Trafford on March 11.

Mourinho said after the game in Milan: "When we go there [to Old Trafford] we will not have the same referee.

"If we have another referee it gives so much protection to the away team, then it will be us who go to the quarter-finals.

"Everything was against us, every little detail. You watch how many free-kicks they had and we had. The way we got yellow cards and they did not. I think the tendency was clear.

"Hopefully in the next game the referee will be on our side."
