It's always both.
This appointment has been just a massive show of weakness from the club imo.
From the very beginnining. The plan when Ole was not to be manager was to adopt the football structure other teams are using, as it was clear it hadn't worked for us. Instead, one an Eredivisie manager with a seemingly good system and one semi-final in the Champions League campaign popped up, as usual we abandoned all our plans and gave him far too much power.
The sad thing is, in sacking Ole we had shown signs of improvement in this regard. Unlike Ten Haag, Ole had shown signs of good attacking performances with the problem usually being a lack of quality in the final third in games where we were camped in the opposition half. We struggled to break those down. Yet the fact was, we were camped in the opposition half. Ole deserved to stay as long as he did, but also deserved to be sacked once he showed that he couldn't manage a progressive side with big personalities.
With Ten Haag, we took a massive step back. His job is to get good and consistent performance from the team. Good and consistent performances come with control and chance creation. The hope for a good manager is that once they can get us playing good football consistently, we can challenge for key trophies consistently, improving in quality enough to where we can expect to win. None of the managers we've hired have even done that bar maybe Jose in small batches of 16/17 and 17/18. Yet we've always treated these managers like players are simply not giving them enough, rather than calling it what it is and seeing that both parties have simply failed to show cohesive quality. The manager's job also entails getting that cohesion, and somehow fans and the media, in regard to United, have always seemingly blamed players for this, as opposed to the managers. Right now, we're breaking negative records, yet people somehow still want to blame players for this. Players who have looked good in other clubs and with their national teams, yet can consistently concede 20+ chances a game at United. The system and strategy he uses sucks and the fact that despite his job being on the line, he's still using it, doesn't show resolve, but rather unseriousness, stubborness or a lack of ideas....or it could be all three. As a fanbase, we expect so little of managers. I hate the fact that's the case, as it exposes the fact that the media painted Sir Alex' success as simple. Like any good manager with time could get a team to play swashbuckling attacking football when given good support. It's quite clear the club thinks that ( with appointing Ole and Moyes) and the fans think that ( with how easily they crown a messiah).
Our problem is when we hire managers, we almost try to prove that we made the right decision hiring them, instead of assessing them to see if they deserve the job. We're more concerned with selling the idea of them to the public rather than ensuring they get us to success. A good club should see an underperforming, poor manager and be able to sack them within 2 months. At United we look for every reason to keep them, use small wins as indicators of success and can keep a bad underperforming manager for 2 years. Giving a manager " time" isn't an indication of a good structure. No club with a good structure would give underperforming managers time. They'd all sack the manager and replace them quickly. Making tough decisions decisively and giving fans faith that they can always make those type of decisions. Player's opinions and training practices are considered. Unlike us, they won't just consistently shut down any news coming from within the club, and treat the opinions of grown adults as petulance from children. Our mentality is still stuck in the 90's which is why we've been operating so badly. The managers don't suffer from this, its the players that do.
