Pep Guardiola is 100% certain and willing to bet "a big, big glass of beer" that Wayne Rooney will play for Manchester United against Bayern Munich in Wednesday's Champions League quarter-final second leg despite the striker having a toe injury.

Rooney was able to train with the team on Tuesday despite David Moyes revealing on Friday that the forward was a doubt for the game.

Rooney suffered the injury in last Tuesday's 1-1 draw at Old Trafford in the first leg. This caused him to miss Saturday's 4-0 win at Newcastle United, with the forward's availability for the deciding leg at the Allianz Arena in the balance.

Yet Guardiola told his Tuesday morning pre-match media briefing that he is convinced that Rooney – and Antonio Valencia – will definitely play.

The Bayern coach said: "He is going to play, 100%. He is going to play – I bet you a big, big glass of beer. I believe he is going to play, and Valencia too. Rooney is going to play. He is a big player."

Ryan Giggs, who has also been struggling with injury, also took part in the session although Marouane Fellaini missed out.

After the training session concluded, Rooney said he was feeling good about Wednesday night's second leg.

He wrote on his facebook page: "Good training session with the lads ahead of the Bayern Munich match tomorrow night.

"It's a massive game for us against a top side but we'll be going in confident and looking to progress into the semi-finals."
