Champions League title holder Bayern Munich has not won a match since lifting the Bundesliga title with seven games to spare. That run includes the 1-1 draw at Manchester United in the first quarterfinal leg and Bayern's first Bundesliga defeat this season, a 1-0 loss at Augsburg.

Bayern is seeking its third consecutive semifinal appearance, while United has not been in the last four since 2011.

Here are five things to know about Wednesday's match:

___

INJURED AND SUSPENDED

Wayne Rooney may need an injection on his badly bruised toe as he looks to return to United's team after missing Saturday's 4-0 win at Newcastle in the Premier League.

"We'll do everything we possibly can (to get him on the pitch)," United manager David Moyes said Tuesday. "He's happy to take an injection to play which I think shows you his feeling about the game and the club."

Rooney took part in full training on Tuesday and United will be desperate to have him back as fellow striker Robin van Persie is also sidelined with a knee injury. Left back Patrice Evra is pushing for a recall having been absent for the first leg through suspension.

Bayern will be without the suspended Bastian Schweinsteiger after the midfielder got a late red card in the first match and midfielder Javi Martinez is also banned because of three bookings.

Also unavailable for the German side are injured midfielders Thiago Alcantara and Xherdan Shaqiri but defender Dante is in contention after suspension.

MISSING FANS

Bayern will be without the support of 700 fans, meaning that the stadium will have a capacity of 67,300.

UEFA ordered one of the sections in the ground to be closed after Bayern fans displayed anti-gay and political banners at the home match against Arsenal in the previous round.

PREVIOUS MEETINGS

Bayern has five titles in the top club competition. United three, one of them won memorably over Bayern. In the 1999 final, United scored twice in injury time to snatch the title from the German side in a 2-1 win in Barcelona.

Bayern coach Pep Guardiola, while he was in charge at Barcelona, twice beat United in the final, in 2009 and 2011.

United has never won in Munich, with Bayern winning two and the other two ending in draws.

ENGLISH TROUBLE

Bayern has struggled at home against English opposition, especially this season. It lost to Manchester City 3-2 in the group stage and that ended a competition-record 10-match winning streak in the Champions League.

Bayern also drew 1-1 with Arsenal at home in the round of 16, after winning 2-0 in London. Bayern also lost 2-0 at home to Arsenal in the previous season's round of 16 but advanced to the next round on aggregate.

They also lost the 2011 final at home to Chelsea on penalties.

UNITED'S TACTICS

The first leg may have finished all square but possession-wise, it was all Bayern. United was forced to defend and rely on pacey counter-attacks, with the German visitors enjoying 74 percent possession and dominated territory.

Still, United had more shots on target than Bayern — 4 to 3 — and Moyes is likely to end up using the same tactics at the Allianz Arena in its bid to pull off either a high-scoring draw or a victory that will send his team through.

It will likely require another huge game from center-back partners Nemanja Vidic and Rio Ferdinand, who produced one of their best performances of the season last week at Old Trafford.

"I'd like to have more possession and have a bigger effect on the game, and my plans are to do that," Moyes said. "But they were also my plans in the first game as well. The quality of Bayern at times was very good. You have to respect your opponents."
