David de Gea – Dave will need to be on top form if Manchester United are to get a result.
Rafael – An interview with the Manchester Evening News calmed fears Rafael will miss out on Tuesday with injury but some more pessimistic comments at the pre-match press conference mean the Brazilian may yet be ruled out. Hopefully he will be fit.
Phil Jones – Despite a minor limp during the match against Aston Villa last weekend, Jones should be fit and ready to start.
Nemanja Vidic – If Jonny Evans and Chris Smalling remain unavailable, then Vidic will probably gain the nod over Rio Ferdinand but neither ageing centre-back is particularly appealing.
Alexander Buttner – With a suspension to Patrice Evra, Buttner is United’s most viable option at left-back and has seemingly been prepared by David Moyes with two recent Premier League starts.
Antonio Valencia – Valencia’s role will be interesting depending on several factors. Firstly, the Ecuadorian will need to be match-fit himself and secondly, if Rafael is injured he may find himself at right-back. Should both he and Rafael be fit however, Valencia will probably start on the right side.
Michael Carrick – Rested for the first half at the weekend, Carrick will inevitably be involved in this match but only in central midfield if he is not required to provide cover at centre-back.
Tom Cleverley – The mobility and energy of Cleverley make him a prime contender to start on Tuesday but Ryan Giggs may provide a challenge to him in that regard. A game at the weekend for Darren Fletcher will probably rule out involvement for the Scot whilst any Marouane Fellaini-related calamity will probably be avoided in advance by David Moyes.
Danny Welbeck – Pace and penetration are what Welbeck brings the team and a rest at the weekend points to him starting against Bayern, probably on the left.
Shinji Kagawa – Like Buttner, Kagawa has been given lots of minutes ever since the Champions League quarter-final draw was announced. His experience of German football, the absence of Juan Mata (cup-tied), Robin van Persie’s injury and a second-half withdrawal against Aston Villa at the weekend all point to Kagawa starting on Tuesday.
Wayne Rooney – Rooney is United’s in-form man and any hope of beating Bayern will rest on him being on song against the German side.
Injuries may well dictate David Moyes’ selection against Bayern, particularly if he has to reshuffle his defence. If everyone is fit then Giggs will probably just miss out on the starting XI, but there is an outside chance he may start ahead of Cleverley or even on the wing should Moyes’ options be limited. Ashley Young is another who may come in should Valencia not be selected in a right-midfield role.
Moyes is likely to opt for his trusted 4-4-1-1 formation after the dire 4-5-1 experiment against Manchester City and if so the roles of Rooney, Kagawa and Welbeck are likely to be fluid and interchangeable. The absence of Mata may not be a huge miss – pace will be essential on Tuesday night and Moyes is likely to pick a front four who can provide that.
