Shinji Kagawa performed so well against Newcastle last weekend it would be unfair on the playmaker if he was missing from the starting line-up for tonight's crucial second leg.
Last Tuesday, David Moyes elected to start Ryan Giggs ahead of the former Borussia Dortmund midfielder and he may miss out at the Allianz Arena.
He shouldn't. Yes Giggs is still very skilled technically, but the absence of Juan Mata means Mancester United need someone like Kagawa whose touch and vision could unlock Bayern's defence.
Pep Guardiola's team are bound to dominate possession, meaning their opponents must make full use of the ball when an opportunity arises.
And the Japanese icon has the ability to create chances for the likes of Wayne Rooney and Danny Welbeck in attack.
Javier Hernandez benefited from Kagawa's influential display at St.James' Park as he finished his team-mate's precise cutback for United's third goal.
Glimpses of quality have been demonstrated, but the No. 26 has had a largely frustrating stay at the English champions.
Kagawa looked an accomplished footballer on his debut against Everton last season, but he was then shifted from central midfield to left wing after injury.
He did score a sublime hat-trick against Norwich, giving him a tally of six goals from 22 starts in 2012/13 along with five assists.
A change of manager has not led to Kagawa playing in his favoured position behind the striker, where he was outstanding at a Bundesliga-winning side.
In his final year alongside Robert Lewandowksi, his creative and scoring capabilities were evident by 17 goals and 10 assists in 42 matches from all competitions.
Dortmund won three league games with Kagawa starting against Bayern, and although he now plays for a different team, his experience is arguably more important than Giggs' 1999 Champions League success.
There will be huge attention to Moyes' preferred XI and you feel Kagawa's time in Manchester could be up if he is sitting next to a team-mate at 19.45.
