Saying Moyes won the Charity Shield as proof that the mediocre managers you listed could win things with a lot of money is really shaky proof sorry to say. The fact is Moyes reign at United shows that a bottomless pit of money is not enough to save a bad manager from failing at a big club. And while the benchmark of winning trophies is a high standard it is still the goal of every club. So if we are going to look at the most successful way of winning then the clubs and managers that do win would be the ones to look at. Saying that the manager runs everything system is the best way because some guy won the Championship with Charlton isn't really going to work. Meanwhile clubs like Bayern and Juventus switch managers without skipping a beat because the top of the club continues bringing in players and running the club.
Pretty much all the greatest British teams have used that setup. Also, Curbishley did not just win a lower league with Charlton, but established them in the top league against better funded teams.
What we have now is the top teams all go for successful coaches from overseas. However these guys are able to work their way up in other leagues, while that doesn’t happen here any more. Our league is now littered with overseas coaches, most of whom offer nothing more than their less glamorous UK counterparts.
And Moyes at Man Utd is not exactly a great example of a bad manager failing with limitless funds. The whole reason he was appointed was to keep the budget approach going so the Glazers could suck more money out of that club. However the squad was past it, despite winning the league. In fact winning that year was one of Fergie’s greatest achievements as a league manager. They then started spending wildly under Van Gaal to try and righten the ship.
Saying he is a bad manager is just stupid - he won three LMA manager of the year awards and did a great job here for years. He might not be everyone’s cup of tea, but he proved he is still a capable coach at West Ham last year. The same people who say he is a bad coach are the same ones who say Hodgson is a bad manager, when he is actually a very, very good manager.
The reason Bayern and Juve can change coaches like underpants is due to their overwhelming resources compared to other teams in their respective leagues. In fact the consolidation of resources is one of the biggest problems in European football, and will likely end with some form of super league at some point.
How are we going to find the next Robson or Ferguson when the leagues are crammed with coaches from overseas?!?
