Sir Alex Ferguson criticised the behaviour of the Bayern Munich players after Manchester United's Champions League exit at the hands of the German side.
United, who lost on away goals having won 3-2 on the night, appeared to be cruising through when they led 3-0 after 40 minutes thanks to goals from Darron Gibson and Nani (two).
But Ivica Olic slotted home just before the break for Louis Van Gaal's side. Rafael was dismissed for a second booking early in the second half and a stunning volley from Arjen Robben saw the visitors progress on away goals as the tie ended 4-4 on aggregate.
Ferguson was furious about the manner in which the Bayern players had put pressure on referee Nicola Rizzoli to show Rafael a second yellow card after tugging back Franck Ribery.
When asked if the sending-off had changed the course of the game, Ferguson told ITV1: "There is no doubt about it. They were never getting through that tie, with 11 men we had no problem.
"The young boy showed a bit of inexperience, but they got him sent off, everyone sprinted towards the referee - typical Germans."
The Scot also believed United had been the better side across the two legs.
"We played better today than they did in their own ground. Without the extra man they made the ball work and I thought we defended very well, it's taken an exceptional strike to settle the tie.
"We have done well, the performance was excellent, we were very unlucky."
Ferguson also played down any fears that Wayne Rooney had suffered a recurrence of his ankle injury.
The England striker was a surprise starter at Old Trafford but was soon limping after being caught in a challenge, he was eventually substituted after 55 minutes.
"We will have a look at it," Ferguson said.
"I don't think it is serious. It's just that tissue and the blood vessel has just burst. I am sure he'll be fine for the following week."
