Munich - After being held to a 1-1 draw at Old Trafford, FC Bayern München go into Wednesday's UEFA Champions League quarter-final second leg against Manchester United FC confident they can get the job done on home soil (kick-off 18:45 GMT/ 20:45 CEST).

"Win, and we're through. Lose, and we're out," head coach Pep Guardiola succinctly told journalists at Tuesday's press conference.

'We'll reach the semi-finals'

It is, in truth, a situation Bayern have not found themselves in for over two years. At this stage last season, a 2-0 win over Juventus FC had given Bayern one foot in the last four. A 4-0 triumph over FC Barcelona in the semi-final first leg meant they could practically plan for a trip to Wembley.

It was the same story two seasons ago, when they carried a 2-0 advantage into the second leg of a Champions League quarter-final against Olympique de Marseille. Cause for concern? Not likely. "I'm certain we'll reach the semi-finals," added Guardiola. "We're the home team and that's an important aspect."

'Got to hold our nerve'

Bayern's first defeat in the Bundesliga since October 2012 does not worry Guardiola either. "Of course I'm sad about it, but our aim for the past three weeks has been beating Manchester," he said. "We've already won the Bundesliga. What matters is tomorrow and the DFB Cup semi-final against Kaiserslautern."

Captain Philipp Lahm added that Bayern will not panic about an uncharacteristic run of three games without a win. "We've got to hold our nerve and we'll go into the game to win it, just like we always have done and always will do," he said. "We go into tomorrow's game with the attitude that we definitely want to reach the semis."

Big players, big game

With "only 14 players available," according to Guardiola, his team picks itself. Defensive stalwart Dante returns after missing the first leg through suspension, but Javi Martinez and Bastian Schweinsteiger are both banned. "We're without so many players and of course that's not positive for the team," Guardiola said. "Bastian's a leader, who's very important to us."

United also have a few injury concerns, but suggestions that Wayne Rooney will not start have been laughed off by Guardiola, who has placed a wager that the English international will be involved. "He'll play - definitely," he said. "I'd bet a pint of beer that he plays. And [Antonio] Valencia will play too. The big players always play in the big matches." And few come any bigger than Wednesday night's at the Allianz Arena.

Possible line-ups:

Bayern: Neuer - Rafinha, Boateng, Dante, Alaba - Lahm, Kroos - Robben, Götze, Ribery - Müller (Mandzukic)

United: de Gea - Jones, Ferdinand, Vidic, Evra - Fletcher, Carrick - Valencia, Rooney, Kagawa - Welbeck
