"It's a big game on Tuesday but it's a chance for me to show what I can do," the 25-year-old said. "It's vital for me to get the two matches [against West Ham and Aston Villa in the Premier League] because it would have been difficult not to play and then to have to face a big game like Bayern.
"I feel confident about playing them. I know what Arjen Robben can do and I'm ready for him.
"I've watched him so I know how he plays the game. He's very good one-against-one, especially when he comes inside.
"I have to focus on that game and be confident in my own quality. I know I can get the better of him.
"It's not under discussion how good he is, we all know that, but this kind of big game is why you play football. It's what it's all about."
