That was before the tv money has leveled the playing field somewhat, as well as West Ham now having a 60,000 stadium they don't actually have to pay for. And both Liverpool and Spurs did upset the applecart to some degree in that it forced the other teams to shell out shitloads of money in a desperate attempt to claw back. City spent 300million in the 2 Windows after Spurs finished ahead of them in CL, ditto United when Liverpool did. Now that the financial playing field isn't so stacked in one favour its going to be harder to do that now that clubs like Wham and Stoke are able to afford and lure the likes of Payet. I don't see there being an obvious natural top 5 anymore, these so called anomalies are going to become more regular.
