The out-of-form attacker has returned to Carrington after an ankle injury and United staff will continue to monitor his progress ahead of a possible recall for Saturday's clash.
Wayne Rooney has returned to Manchester United training with a view to playing some part in the Premier League visit to Bournemouth on Saturday.
The England captain picked up an ankle injury in the 1-1 draw at Leicester in late November and was originally expected to be fit to play in the home match against West Ham seven days later.
However, manager Louis van Gaal admitted last week that the “nasty” injury was worse than first thought and ruled the front man out of Tuesday’s crucial Champions League visit to Wolfsburg as well as the 0-0 draw with Slaven Bilic's side.
