People were far to premature to call a power shift in North London because of this transfer market, it's still Arsenal 4th and Spurs 5th for me. What will be Tottenham's downfall is their defence, their fullback's can't defend to save their lives, Vertonghen isn't a good defender (a fact that gets covered up by his goals), Dawson isn't more than a squad player for a team looking to challenge for top 4 and Kaboul has been out for a year, there is no guarantee he won't go the same way as Essien. Lloris has been superhuman so far this season, but over-all Spurs have been awful.
