Its a bit of a double edged sword. They are massively reliant on him, but at the same time i cant imagine hes a positive influence in the dressing room right now
Maybe i've forgotten, but it seems like from 2000 onwards they seamlessly transitioned from one great team to another, both by producing some exceptional talent on their own and by purchasing the very best in the world. This time though, it seems they've hit a couple of snags on the road and the team they field today is significantly weaker than the ones they had 5, 10, 15 and 20 years ago
Essentially what happened to us. The big thing is for a team to never reach that point where a rebuild is necessary. I think that, more than anything else was our mistake. We didn't even try to replace key players when they were getting older ( in the same way Barca have done with their midfield and defence). They are also putting too much faith in youth in the rebuilding process too. We tried this with Jones, Smalling, Cleverley, Januzaj, Shaw, Rashford. It doesn't work. You spend too much time waiting for these players to develop if they don't have more reliable players in the team already who have established themselves. Even with Fergie's 96 team, we still had Schmeichel, Irwin, Bruce, Pallister, Keane, Giggs, Cantona and Cole...8 fully established players. Arsenal also made that mistake from 2006/07 to 2013 and are literally still paying the price for that policy today. The chance that even one player establishes themselves is slim, trying to do this with more than 4 is almost impossible, United got lucky with that group...same with Barca with the Pique, Busquets, Pedro, Messi group.
