United boss Louis van Gaal has called for better consistency from the Reds ahead of the visit of basement boys Aston Villa to Old Trafford.
At the end of a positive week that saw United into the FA Cup semi-finals, LVG said that he was "happy" with his side's standing but that the lack of consistent form has been "frustrating".
"The players, the manager, the staff and the fans also have been frustrated because we have not been consistent this season.
"When you have to line a different team up every week because of injuries, it is difficult to make a consistent team-building process.
"Still we are in the race for the top positions in the league and we are still in the FA Cup so we have to be happy with our season.
"I'm very happy that we have the ability to pick young players out of the Academy, this is something I always do and Manchester United believes in youngsters, so it is not difficult to do this." said the Dutchman.
The managerless Midlanders arrive at Old Trafford in turmoil.
They've won only three league matches all season, they've been rooted to the foot of the table since September and defeat here would confirm a relegation that's looked inevitable for months.
15 points adrift, they could even be down before kick off if Norwich get a result against Sunderland in the lunchtime game as the former European Cup winners face a first ever season in the second tier after a desperate campaign.
Tim Sherwood was sacked in October and replaced by Remi Garde but the Frenchman was unable to save them and left the club last month to leave Eric Black in temporary charge.
Wayne Rooney returned in midweek and is available but Ander Herrera is a doubt and Bastian Schweinsteiger will miss the rest of the season.
Luke Shaw and Adnan Januzaj have returned to training but are some way off a first-team comeback whilst Phil Jones is pushing for inclusion after an Under 21 outing on Monday.
Herrera picked up a knock in the midweek replay but the extent of his injury is known- however, with Crystal Palace on the horizon on Wednesday a rotated team is possible.
Jordan Amavi and Gabby Agbonlahor will not feature for the visitors but Jack Grealish and Adama Traore have been passed fit.
