The experienced left-back was suspended for the first leg against the Bundesliga winners, with Alex Büttner performing admirably in the Frenchman's absence, and has been struggling with a knee problem.
"I think I will be fit," he told manutd.com. "I received a knock and I was injured as well before Aston Villa with my knee so I will try my best to be fit. Sometimes you have to play your best and be honest with yourself and your team-mates. If you are ready to play, you have to give everything. No excuses. If you play a bad game, you can’t say it was because you were injured.
"First of all, I was really frustrated to not play in such a big game [the first leg] but I though Alex did a good job. I was so pleased with the performance of the lads and now we must make sure we pull off a shock because Bayern are favourites for this game. It is not often since I have played for Manchester United that we are not the favourites but, sometimes, you have to accept they are favourites and let’s surprise everyone."
