The Reds have been drawn in Group A alongside Shakhtar Donetsk, Real Sociedad and Bayer Leverkusen, who visit Old Trafford on Tuesday evening. And Moyes, whose previous experience in the tournament was with Everton in 2005, acknowledges it’s going to be tough.
“I've been excited about it ever since I've joined Manchester United," he told reporters on Monday. "Every game has offered a new challenge and a tough one as well. I've been there before with Everton - we didn't quite make the group stages but this is different. This is a club that's used to getting to the latter stages.
“I think all groups are tough. You used to be able to always pick out the group winners but in the last few years that has become more difficult. It is more unpredictable than it was. We've got a leading team from Germany, one from Spain and we go to Donetsk to play Shakhtar. It's a tough group.
“I think it's become a competition that everybody wants to do well in. Maybe some teams can afford to rest players in their leagues and use them in the Champions League but that's hard in the Premier League. It's a competition the players here at Manchester United are used to and experienced in.”
