Towards the end of the transfer window I was admittedly quite critical of their summer transfer activity.
They signed what was a massively short term option in goal, a potentially problematic striker who's attitude has proved to be an issue in the past - on loan - and Scott Parker.
In hindsight though, the three of them have made an absolutely massive difference to Spurs, along with Ledley King managing to keep himself fit for what (for him) is a relatively long period of time.
If one of these main players were to pick up an injury though - Parker especially - I think we might see them struggle a little more. Like others have said, they do undoubtedly have a very good first eleven, but for me, they're still quite light in certain areas beyond that.
They're going very well right now though and, like Arsenal, have recovered brilliantly following a shaky start and some heavy defeats. I'd put them in as favourites for third as things stand. I still don't think they're capable of mixing it with the two Manchester sides though.
