His recruitment, while not great and somewhat overrated on here, has definitely been better than his predecessors and he's largely removed the toxicity around the club, we've been relatively stable and in the top 4 under Ole while there have been some really enjoyable games since he took over (more than under any manager post Ferguson) .
However I think the idea of him undertaking this "cultural reset" is largely bollocks though. We haven't had any young players really make a breakthrough since Greenwood, who played in the PSG game, and there's no evidence yet that the relatively minor changes to the structure at the club have made any difference, the only place where we can see the culture created is on the pitch and I'm not sure it's that positive.
There seems to be a culture of favouritism in the teams he picks, where certain underperforming players face no consequences for bad form which shows that there is no meritocracy in team selection, allied to a culture of expecting players to play when injured and playing players who aren't fully fit (Rashford in the previous two seasons, Magure in 19/20 and now him and McTominay along with other examples).
But they all arise from the main issue, a culture where the idea of modern ideas and progressive coaching are dismissed as "hipster" opinions (he hasn't said those words but he's always very dismissive of the value of tactics and coaching and it's a term his staunchest defenders have used) in favour of nostalgia and old-school values. There is no system or cohesion so players can't slot in when needed, as Liverpool did with Milner, Jota and Konate yesterday, and so he has to keep resorting to the same players who have delivered individually at some stage in the past, regardless of form or fitness.
As noted in the first paragraph he has done some things well but it's now time to move on, if that time hadn't already come, and bring in a manager who is going to create a coherent team who look like they've developed something in training and are actually learning and improving on a daily basis.
