Shinji Kagawa says he is looking to make up for his failure in the Champions League last season.
"I'm looking forward to it," he told United Review. "If I'm picked I'll do my best to help the team reach the next stage of the competition.
"I played in the Champions League with Borussia Dortmund last season but unfortunately we couldn't perform to our potential.
"We were too young, we didn't have enough experience and got knocked out in the group stage."
He added: "United has a great history and we finished top of our group this season.
