In another thread I basically compared Allardyce at bolton and Moyes at everton in 2001-02 to 2006-07. Moyes spent 1/3 more money but it was comparable amounts and they finished in about the same positions (average 9th place for both of them, though Moyes did slightly better).
And then Allardyce left and struggled in other clubs where the fans turned on him and he couldn't get players to buy into his system where as moyes has if anything got better and made us much more consistent.
You could argue that's simply class telling (and that once Moyes cleared out smith's side and built his own he was always going to pull away) but for me Moyes was in a better position to push on simply because he hadn't changed clubs. Because every player at the club was bought in by moyes, every member of the backroom staff was bought in moyes, every penny spent was approved by moyes, every wage negotiation Moyes would be consulted. He doesn't have to prove himself to anyone, he doesn't have to make players buy into him, they're his players. And there aren't players who the previous manager has spent money on and put on a big wage who moyes doesn't fancy. Every penny we spend goes on a player Moyes wants.
The fact is overachieving in the Pl is a lot easier than it should be because so many clubs are so badly run, see sunderland or Newcastle or villa or the RS. All of whom have expensive players on big money who the current manager doesn't want (Hi Bent, Hi Carroll.) We don't have that which is partly why we get value for money.
True to a point but when Moyes inherited a relegation battling side, one season apart he turned us around without having his own players, in fact losing our best player. We were doing well under him long before he had fully replaced the personnel, and that he now has the players he can afford doesn't mean he should be doing better positionally in the league than when he took over though.
The reasoning behind this is simple.... Spurs, Liverpool, Chelsea, City, United and Arsenal have consumed vast sums of money.. Moyes has sold some players to pretty much break even. Surely once that plateau has been reached where he has his own team that he spent 5 quid on, every season there onwards is harder..
Selling Arteta for 10mil and buying Mirallas for 8 is not quite the same as just wanting Hazard so we'll get him, I fancy having Dzeko at our club.. and Aguerro. That is a year gone, next year... sell Baines, get two players that are his whilst Messi joins United under Klopp or whatever.. How should that extra year in charge mean we should be the ones that improve most there?
Bale is good, lets spend whatever he wants to keep him say Spurs. Rooney and RVP v Anichebe and Jelavic.. Whilst these are Moyes own players, it doesn't come close to making up the gap produces by the finances of others.
Being at a club for another year with no money and the expectation to improve, is not even close to being as easy as being at a club for a year with an extra 50mil to spend on a quality squad.
