Neither have overseen particularly strong starts and both are trailing in the wake of leaders Liverpool and Manchester City.
These two in fact are in more of a battle for the top four than the title.
Arsenal would at least move into the top four with a win tonight, but United currently sit in the bottom half of the table on just eight points from six games.
Will either boss be sacked if they lose tonight?
Neither Ole Gunnar Solskjaer or Unai Emery will be sacked if they lose tonight’s Premier League clash at Old Trafford and neither man should be.
Why? Because the problems they inherited at their respective clubs meant that they were always going to need time to sort out the mess.
And because no organisation in their right mind would allow their boss to spend £145million (Solskjaer) and £181million (Emery) in squad overhauls, respectively then sack them at the first sign of a wobble.
Emery has had a full season at Arsenal and brought about an improvement of one place and seven points on Wenger’s final campaign.
They are leaking too many goals to make things comfortable but the fans are onside with it.
United have problems at the other end but the fans are onside with the Norwegian and as long as that is the case.
The respective strengths and weaknesses suggest something might give one way or another tonight – we could be in for a thriller – but neither man will pay for it with their job.
No. Both teams need to take a look at Liverpool.
Jurgen Klopp has got the Reds firing with a team that he made and it was not an overnight success. He was given time and resources to do what he wanted with his team.
Solskjaer should never have been given the Old Trafford job in the first place, but now he has he must be given the same chance to succeed.
Both United and Arsenal also need to lower expectations. The Premier League title is not a reasonable standard to set.
Set a target and look to achieve, step by step. There’s too many chairmen quick to pull the trigger at all levels of football and it very rarely works.
I think there’s a bigger case for Unai Emery being sacked at Arsenal than there is Ole Gunnar Solskjaer at Manchester United.
While both clubs are in a rebuilding phase, United are just starting under the Norwegian and he deserves the full season at least.
Emery has already had that at Arsenal and personally I’m struggling to see the progress being made.
Admittedly, the Arsenal frontline is lethal but there is only so much the likes of Pierre-Emerick Aubameyang and Nicolas Pepe can do in covering up the defensive frailties.
Emery opting for David Luiz in the summer rather than properly reinforcing could cost him his job.
Having said that I expect both will continue after tonight’s clash at Old Trafford.
Ole Gunnar Solskjaer is more in danger of the sack than Unai Emery if his respective team loses at Old Trafford tonight.
Arsenal haven’t won away at United in the Premier League for over 13 years and have not won on the road against a fellow top-six side since January 2015 – a run spanning 23 matches.
The optimistic Arsenal fan will say it is a great time to play United, and it is. But Arsenal on the road are a different kettle of fish to when they play at the Emirates – just look at their second half at Watford for an example.
If Arsenal lose it will just show the problems that have been apparent for years, going back to Arsene Wenger’s reign.
United, meanwhile, have what it takes to punish the Gunners’ weak defence, despite a number of injury doubts. But if they don’t, and the visitors come away with all three points, then Solskjaer is in a fight to save his job.
