The Reds seemed to be in a positive mood despite the wet and windy conditions and the disappointing result against Liverpool two days ago. A game of 'boxes' (keep-ball) was the first exercise for the outfield players, with Nani and Javier Hernandez among them following their return to training - as revealed by Moyes on Friday.
Wednesday's match is another crucial one for United who go into the last 16, second-leg clash with the Greek champions at Old Trafford 2-0 down from the first game three weeks ago.
