Abramavich was apparently considering buying Spurs, but was able to get his hands on Chelsea quicker - apparently the latter were thirty minutes from financial meltdown when Bates concluded the deal with him. So it's easy to remove Chelsea from the list.
Blackburn had, for a while, the income of a big city club, courtesy of Jack Walker's largesse. However, once he had his trophy in 1995 JW wouldn't invest much more, and had some rather"old fashioned" attitudes - he refused to authorise the signing of some player by the name of Zidane from Bordeaux on the basis that Rovers didn't need "them foreigners".
Leeds and Newcastle had unsustainable financial models: Ridsdale's Elland Road regime was based on reaching the Champions League semi-finals every year, and at St James Park the Hall and Shepherd system seems to have consisted of increasing debts, and taking a great deal of money out of the club - Ashley didn't perform due diligence, and got lumbered with paying off c£170m of debt.
Randy Lerner has spent a lot at Aston Villa in an attempt to replicate the success of the Cleveland Browns: mostly pissed away on bad signings and enormous wages.
Spurs instead of Chelsea is the best bet, with the latter doing a Portsmouth without the Russian money.
