Wow that's fear. If there's one thing I gree is that we lack personalities that have a winning mind, but honestly I can see Jose fix this quick.
While I've criticized him a lot, I don't doubt that he's one of the best managers. But I think a lot of the problems besetting this club can only be fixed over years, not in a couple of transfer windows.
One of the big problems that jumps out at me is that the senior players who you'd think of as 'United' players (Rooney, Carrick, Valencia, etc.), several of them are older and on their way out of the club. I don't think it's any coincidence that Rooney, Carrick, and Valencia played such a key part of winning our last 2 cup finals. 2 of them are past it but they still have some understanding of what it means in those kinds of games.
The veteran players who will be left (Ibra, Mkhitaryan, Herrera, Blind, etc.) either came here during one of the last 2 managerial turnovers or just joined the squad this season. De Gea is an exception, he joined the last of SAF's teams while at a young age, so we, hopefully, keep him in the team for a few more years.
This kind of shuffling makes it impossible for any manager to build any kind of psychology with a team. Our only consistent captain over the past few seasons has been Rooney, who IMO has been wanting in that role. It's no coincidence that Ibra came right off the airplane and immediately became a leader in the dressing room. There are just not enough authoritarian figures in the squad, if any, to drive the team and with players in and out so much it's hard for any personalities to emerge.
It's going to sound sentimental, but having good players who were developed in your own system also means a lot. The title-winning squads SAF fielded would have been completely different if players like Scholes, Giggs, G. Neville, were not playing for us - or perhaps we wouldn't have won those titles at all. This is where our academy has largely failed. I think Rashford will be a good player, but the PL is currently littered with rejects from our academy like McNair, Love, King, Campbell, etc. who are not up to the standard we need. We have a few fringe first-teamers like TFM and players like Pereira on loan, but none of them look any kind of certainty to make it. Lingard is a decent squad option but I think he's overrated just for the fact that he's 'made it' at United.
I'm not a very sentimental guy, but when you have no clear leaders in the team for long term and a squad of players who have been around for all of about 5 minutes (and may very well leave soon), with no real sense of being a 'United player,' who provides that extra for the shirt? I know this is a dying idea in football nowadays, but the culture at United now is that
no one wants to go that extra 10 yards. When players come to us from elsewhere on transfer, I doubt they see players when first in the dressing room that jump out at them as real leaders, real game-changers. The current makeup of United, from the owners to pitch level, is soft. Except when we need to spend ridiculous amounts of money...
