Form guide: The Reds travel to Bavaria buoyed by the comprehensive and clinical 4-0 win over Newcastle, delivered by a side showing eight changes from the one that started last Tuesday's Champions League draw at Old Trafford. Bayern boss Pep Guardiola also shuffled his pack for his team's last outing, but the the German champions slipped to a 1-0 defeat at Augsberg, which ended their 53-game unbeaten run in the Bundesliga. Goalkeeper Manuel Neuer shrugged the result off, saying: "It's all about Wednesday and the match against Manchester United. Nothing else matters," but his side are now without a win in three outings. They have also failed to beat English opposition on home soil this season, losing to Manchester City and drawing with Arsenal, although the latter result secured an aggregate success in the last round.
Ins and outs: Juan Mata is cup-tied, and Ashley Young could be a doubt after tearing ligaments in his hand at St James' Park on Saturday, but Patrice Evra is available after missing the first leg through suspension. David Moyes will give Wayne Rooney every chance to recover from the damaged toe that kept him out on Saturday and he trained in Manchester on Tuesday morning. The form of Javier Hernandez, Shinji Kagawa and Adnan Januzaj gives the boss plenty of options. Bayern's midfield will be without the suspended Bastian Schweinsteiger and Javi Martinez, but defender Dante is available after serving a one-match ban.
