Blowing it well out of proportion there, Dan. Villa only have to drop back to a wage bill of approx. 60% to start breaking even again, down from 80%+, whilst Lerner has blown absolute shedloads of money on players over his tenure. All they're doing now is returning to pre-Lerner levels of finance, which was still better than Everton.
Martin O'Neill basically spent multi-millions on relative garbage, Lerner hasn't seen a return so he's scaling back. The only difference between Villa and Spurs is that Levy and co. have seen improvement on the pitch whilst Villa haven't, with only a 6th-placed finish to show for their blown cash.
Rumours of Villa's demise is greatly exaggerated. Indeed, the sale of Young in the Summer with the cash injected into backing the wage budget will steady them almost completely, whilst still being able to outspend Everton with ease.
The difference with Villa and Everton's board... Lerner has thrown £40m a year at Villa in player purchases and running costs, Grantchester/Green are impeccably invisible.
There's wealth, and then there's wealth in football.
He hasn't. The figures you'll Google are sensationalist nonsense.
Either way, what he has spent is mute in this point of Moyes. He's stopped. In good time too. As wages account for nearly 90% turnover. I'd speculate he's more likely to sell than to invest any more.
