Bayern Munich manager Pep Guardiola is certain Wayne Rooney will be fit to play for Manchester United in tomorrow Champions League tie.
The England forward is a major injury doubt for the quarter-final tie after sustaining a foot injury last week.
Rooney missed Manchester United's 4-0 win over Newcastle United but was reportedly back in full training on Tuesday morning.
While it remains to be seen whether Rooney will travel with David Moyes' squad to Germany, Guardiola says he is already sure United's key man will play a role in the second leg and is willing to put his money where his mouth is.
Speaking in a pre-match press conference, Guardiola said: "Rooney is going to play, 100 per cent.
"He is going to play, I bet you a big big glass of beer."
As previously stated, Rooney took part in training at Manchester United's Carrington training ground on Tuesday morning, providing a big hint that he is fit to start against the Bavarian club on Wednesday evening.
Manchester United go into the game needing at least a goal to advance to the semi-finals following a 1-1 draw at Old Trafford last week.
Rooney is considered key to Manchester United's chances in the Allianz Arena, with reports suggesting that the 28-year-old will play through the pain barrier in order to help keep the fallen Premier League champions alive in what is their last chance for silverware this season.
