Manchester United manager David Moyes is hoping to conquer all the odds when he takes his side to the Allianz Arena to face Bayern Munich on Wednesday.
Most of the football world assumed last Tuesday's first-leg would be a walkover for the German outfit, but Moyes won the tactical battle over counterpart Pep Guardiola in a 1-1 draw.
But the Scot now admits that he may have to change tack in order to guide United to their first Champions League semi-final since 2011.
"If you look at the recent history of the Champions League, you can see when teams sat back, waited and waited and got something from games and got through,” he said.
"So I don’t think there is any shame in what we did at Old Trafford, not by a long way. Tactically, we played very well on the night but we might need to think differently in the second leg.
“A change of strategy is something I’m looking at. Pep will probably alter things and use players in different positions. We have a decision to make as well and that’s something I’m mulling over."
The bookmakers still make the formidable Munich side 1-9 odds on favourites to progress, but Moyes has at least given the fans hope that they can cause an upset in Germany.
Bayern failed to score for the first time in 74 matches in a 1-0 defeat at Augsburg on Saturday - just their third defeat from their last 46 games - and Moyes feels the first goal in the second leg is vital.
He said: "We have to try to get the first goal in Munich because that would put us in the driving seat. It doesn’t have to be in the first minute but we need it somewhere in the game.
“We don’t want to concede first and feel that we have to go chasing the game. That could be a very difficult thing to do against Bayern because they are so good with the ball. It’s such a big prize and we are going to try everything we can on the night to get through to the semi-finals."
Moyes can take solace in the fact that Manchester City won there back in the group stages, and fellow Premier League outfit Arsenal also avoided defeat with a draw in their second leg in Munich at the knockout phase.
