The Moyes era was practically a different era of football compared to these days. Back then it was a top 4 not a top 6 and the money that was invested/being thrown about clubs was nothing like it is today. All the clubs have a lot of money these days, back then only a few had serious money. You could pick up a half decent player for a few million whereas the basic benchmark is double figures these days.
You still can now you just have to be brave.
