The Scot could do with a stirring Red Devils comeback in the second leg of the Capital One Cup semi-final after defeat to Chelsea left them 14 points off league leaders Arsenal
Moyes' men have been off the pace in the Premier League, going down 3-1 at Chelsea on Sunday to leave the defending champions seventh, and they were also knocked out of the FA Cup at the first hurdle by Swansea City in what has been a poor start to 2014.
The Capital One Cup is Moyes' only realistic hope of silverware this term, and they are still in the Champions League, but his charges will need to come from behind to progress against Sunderland, having been beaten 2-1 in the first leg at the Stadium of Light.

United have lost four of their last seven home games in all competitions and will likely need to be on top form for the visit of Poyet's men, who have lost just one of their last 10 outings.
Despite Sunday's setback at Stamford Bridge, Phil Jones remains confident United can salvage something from the club's season - starting on Wednesday against Sunderland.
"I don't think we're a long way away from the teams at the top [of the Premier League]," Jones told the club's official website.
"Now we have to bounce back and we have an important game on Wednesday night.
"We're not a million miles away, I'm telling you, but we need to stick together if we're going to turn it around."
One of the main threats to United's progression is likely to be former Manchester City winger Adam Johnson, who has five goals from his last four games.
After scoring a hat-trick against Fulham on January 11, Johnson was Sunderland's hero on Saturday as he netted the equaliser against Southampton in a 2-2 comeback to earn a point and make it four games unbeaten.
Excluding an unlikely West Ham comeback, progression for either side would set up a final against Manchester City at Wembley, with Sunderland eyeing their first Capital One Cup success and United their fifth.
Despite never having won the competition, Sunderland have reached the semi-finals on three occasions, making the final once back in 1985.
