Shinji Kagawa and Darren Fletcher were among the Manchester United squad training this morning at Carrington.
Japan midfielder Kagawa has not figured since the Community Shield win over Wigan last month and missed Saturday's win over Crystal Palace with a mild flu virus.
However, it does appear Kagawa is in contention to face Bayer Leverkusen on Tuesday night in what will be David Moyes' first group game in the competition.
Absent from training on Monday morning were Danny Welbeck (knee) and Phil Jones (ankle), while 18-year-old Belgian Adnan Januzaj was not present either, Moyes having opted not to select the 18-year-old in his Champions League squad.
