The fixture list has been exceptionally kind to them so far. Which isn't to detract from a stunning series of results, it's just a little harder to read if they can carry this through. Luton for them next followed by Fulham then Blackburn. The latter of those two should give us a better insight as to where they sit.
I'm always a touch wary of writing off an unexpected team off with the old 'they don't have the squad depth to cope for the whole season' reason. That's what we heard from fans of every other club back, well you know when.
