Form: By their lofty standards, Bayern have suffered a dip in form and are winless in their last three games since wrapping up the Bundesliga title two weeks ago with a record seven games to spare. A 3-3 draw at home to Hoffenheim was followed by the 1-1 first-leg draw at Old Trafford against United before Bayern suffered their first Bundesliga defeat in 18 months on Saturday when they lost 1-0 at Augsburg to end their 53-match unbeaten run. Coach Pep Guardiola has described Wednesday's match as "life or death" for his team and even with the Bundesliga title in the bag, his first season in charge will be deemed a failure if they fail to defend the title. In contrast, United are showing signs of improvement having held Bayern at Old Trafford, then beaten a desperate Newcastle side 4-0 away on Saturday.

The result still leaves them 17 points behind Premier League leaders Liverpool, but David Moyes has the chance to redeem himself after a wretched first season in charge by claiming Bayern's scalp.
