Michael Owen sat out the session as a precaution after picking up a minor groin strain, while Ji-sung Park missed out with a virus that looks set to keep him out of Wednesday's Group B tie against the Bundesliga champions.
Patrice Evra has also been suffering from the bug since the win over Stoke, but the left-back was full of vigour as he joined 22 other Reds on the training field, under the watchful eye of Sir Alex and his coaches.
Edwin van der Sar enjoyed a solid workout as he steps up his recovery from a broken hand, and the only other absentees were Rafael, Owen Hargreaves and Gabriel Obertan, all of whom are due back in the next few weeks.
