Ole Gunnar Solskjaer's men have been on a monumental run as of late, with the highlight being their 3-1 win at the Parc des Princes against Paris Saint-Germain to see United through to the Champions League quarter finals.
The Red Devils' domestic form has also seen them rise to fourth but Arsenal are just a point behind them with Chelsea also in the mix.
Unai Emery has seen his fortunes change drastically after impressing early on with a 22 game unbeaten run.
Arsenal were comfortably beaten by Rennes in the Europa League and with top four not guaranteed, could have scuppered their chances of Champions League football next season.

Ex-Arsenal defender Martin Keown has had his say on the game and believes that despite United's impressive feat against PSG, there were visible weaknesses that can be exploited.
"Their defence can be exposed if they are put under pressure," Keown told the Daily Mail.
"Emery’s best chance of success is to return to the tactics which proved so successful in the 2-0 win over Chelsea.
"That day, Arsenal used Pierre-Emerick Aubameyang and Alexandre Lacazette as inside forwards with Aaron Ramsey breaking from midfield and forcing opponents into mistakes," Keown added.
"Solskjaer will be well aware that Arsenal are a different animal at home. Buoyed by the crowd, they fly forward and take the game to the opposition."
Falling back on personal experiences, the no nonsense centre back remembered an important victory over United that propelled the Gunners to title glory.
"Arsenal must prove they have the character and personality required to be successful. Victory will give them belief that they can finish in the top four, just as beating United in 1998 gave us the belief that we could win the title."News Now - Sport News
