a match he admits would be "a dream" to play in.
"I think everybody wants to play in a big game like this," he said. "I’m always ready. I train hard every day and even do extra training, so I’m fit and ready when I have to play.
"I might do some extra sprints or some extra work in the gym after training. You need to make sure you’re ready if you’re asked to play.
"It’s going to be a tough game against Bayern but we have to be confident and I’ll do everything I can to stop Arjen Robben and help the team get a win at home. I hope we can beat them.
"For me, this will be one of the biggest games I’ve ever played. I’m looking forward to playing against Bayern Munich. I think everybody dreams to play against them."
Büttner feels both he and the team can take a lot of positives from the 4-1 win over Villa.
"It was great for our confidence that we beat them," he added. "If we had lost the confidence would have been low but now we have a good feeling.
"I have played two games now and I thought I played well against West Ham and Villa, putting in some good challenges. It has been vital for me to get the two matches because it would have been difficult not to play and then to have to face a big game like Bayern.
