Manchester United will face major obstacles in making this happen. United's rivals, Tottenham and Aston Villa, should consistently fail to accumulate points. Tottenham is only 6 points ahead, united while Aston Villa is 9 points to the united. The main issue is that the remaining matches are becoming fewer, and it is extremely difficult for Manchester United to overtake Aston Villa and Tottenham considering fewer matches remaining make it even harder and mu potentially widen the gap.
Things at least look better for Manchester United as if they win their delayed match, they will have only 6 points less than both Aston Villa and Tottenham Hotspur. It is a smaller gap than weeks ago and with 9 more matches, Manchester United can hope that Aston Villa and Tottenham Hotspur will lose points because these competitors are not stable in their performances.
However, Manchester United must get nearly perfection in their rest matches and it is very challenging task for them. If they can not do it, dropped points from two competitors might not be helpful for Manchester United to improve their ranking at all.
Manchester United are not consistent with their own games, they can't go 5 straight games without losing a game. While they are waiting for Aston Villa and Tottenham to drop points, I can bet that Manchester United will be the first to drop points. Manchester United inconsistency in the earlier part of the season was the reason why they are still in this position. While they were losing Aston Villa and Tottenham were busy gathering points. It is really going to be difficult for Manchester United to overtake two teams who are determined to grab the champions league spot. But this is football anything can happen, but to be realistic it will be difficult for United to overtake Aston Villa in the top 4.
