I think it might yeah.
But this is it, who would you bring? Annoyingly for us the likely movement in top managers will probably be the season after next rather than next year alone.
Simeone must call time eventually on Atletico, Allegri will make way for Zidane soon enough. Poch may well feel he has taken Spurs as far as they can go if they continue to not win trophies. But it'll take a couple years.
If it were up to me, I'd gamble. Which I was against after the Moyes debacle, I wanted a proven winner but that doesn't really work out well for us, seemingly.
Get a director of football or call it whatever you want, head of football operations, I don't care. Make it clear that we want to play proactive, skilful, "technical" football, looking to sign players who fit that bill (good on the ball, dynamic, energetic) and are young enough to spend their entire peak at United. No more plugging leaks with the likes of Matic.
Then get a manager who fits the bill with that concept. It doesn't have to be someone who won the CL half a dozen times. If he demonstrated that he can get his teams to play the sort of football we're looking for, and that he can elevate a team above the sum of its parts then that should be good enough (not just any team, obviously, should be from one of the major leagues etc.)
Can't give you names I'm afraid. But it would be a better approach, overall, than just looking at the out of contract managers and getting one with the most glittering CV.
