The Reds begin March on a Wednesday night in Newcastle and, despite dominating the game, look set to drop two points they can ill afford to do with revitalised Liverpool breathing down their necks.
Step forward Ashley Young- often despised by opposition supporters and often derided by United fans.
The former Villa man is enjoying a renaissance under LVG however, and makes the crucial difference here when he smashes in a late winner to break the deadlock and seal a massive three points for the Reds after a string of fine saves from home stopper Tim Krul.
The Reds look good in the league, but there is cup disappointment when Arsenal steal victory in a heavyweight quarter-final contest, former United man Danny Welbeck knocking ten man United out of the FA Cup on a controversial night at Old Trafford.
Van Gaal's side are still below their best and finish March with two make or break games, massive six pointers against two sides both still in contention for a top four finish.
First up, Tottenham at Old Trafford on the 15th....
Reds fans needn't have worried, though, as LVG's men, playing a new 4-3-3 system, tore into Spurs and blew them away with flair, pace, style and panache in a breathtaking performance.
Marouane Fellaini continued to prove his worth with his fifth of the season, Carrick headed in the second and Rooney completed a comprehensive victory as United storm to a 3-0 win.
Having dispatched Spurs in some style, United then travelled to Anfield to face a Liverpool side who went into the game one place and two points behind Van Gaal's side.
The Reds end the month five points clear in fourth spot, thanks to two goal of the season contenders from Juan Mata that rendered Daniel Sturridge's late strike irrelevant, Steven Gerrard having earlier been sent off 38 seconds after coming on.
