But this is the time period we are operating in. It is all very well saying Derby won in the 1970's but there weren't oligarchs pumping literally hundreds of millions of pounds into rival teams. There are 3 teams who have qualified for the Champions League every year since Moyes took over. That leaves one space free and Manchester City (£200m wage bill, £150m average net spend on fees), Liverpool (£130m wage bill, £40m average net spend), Spurs (£95m wage bill, £20m average net spend) competing with Everton (£60m wage bill, £2.5m average net spend). That really isn't an open competition.
But even if we accept your strange methodology of ignoring how the squad was assembled it still isn't a fair comparison. Over a 10 year period only Manchester United, Chelsea, Arsenal and Liverpool have won more points than Everton. So we have the 5th best points total on about the 10th highest spend. That is phenomenal. No other manager in Premier League history (i.e the time period we are in) can match that performance.
And by the way there is a heck of a drop off between the spending of Manchester United, Chelsea, City, Liverpool, Arsenal, Villa, Tottenham and Everton. Our budget is closer to Southport's than it is to Liverpool's yet we've won more points over the last 3.5 years.
It is like racing Ferraris in a Focus and still beating half the field.
