The biggest suprises were the spending of Spurs, Villa and Sunderland.

Bollocks, I spent 5 minutes spreading the figures out so they could easily be read! It's probably easier to understand if you click on the link.
The table below represents the clubs per season net spend on purchasing players from the beginning of the premiership season 1992/93 to date. Purchases is the total spent on buying players, sold is the total received from the sale players and net is Purchased minus sold giving a total of the money spend on players . The per season column gives an average of the money spend in each season in the corresponding period. If you click on the teams name in the left hand column of the page you will get a precise breakdown of each individual clubs transfer details.

The table below represents the clubs net spend per season from the beginning of season 04/05 to date. Some users have questioned why we picked that timeframe to analysis. Season 05/05 is the year that Rafael Benitez became Liverpool Manager. Following his comments to the media about his lack of lack of funding in comparison to his competitors I constructed this table to see if what he was claiming was factual. Purchases is the total spent on buying players, sold is the total received from the sale of players and Nett equals the Players Purchased minus Players Sold giving a total of the money spend on players.
The per season column gives an average of the money spend in each season in the corresponding period season 04/05 to date

Maybe we can disregard some Spurs income, seeing as a whack of it came from United.
