I don't really care that Spurs and Newcastle are spending silly money comapred to us because a club like Spurs must be building a mountain of debts since they are not in Europe. Newcastle has a high revenue because they can fill some 52,000 Geordies every home games - the benefit of being the only EPL team in a city like Newcastle, whereas Spurs have a few neighbours neraby in north London (big and small). being the clubs that they are, perhaps they have to offer more money to tempt their transfer tatgets than the top 4.
These clubs are gambling in the transfer market with big transfers and if the situation persists - both failing to qualify for the CL following seasons, they will not be in the best of financial health, to put it mildly.
As for us, with Schevchenko and Ballack in the team, Chelsea will have to play a more open game than Mourinho's favoured pragmatic but tight 4-5-1. Schevchenko does not play upfront alone and always will have a partner alongside him - due to this, teams will have more of a chance to score against Chelsea. At least a costly-players packed Spurs will have more of a chance of taking points off Chelsea.
Bring on the new season.
