I think we're probably better set up to survive already than teams like Sheff U and Luton (and possibly even Burnley tbh), in that the players we've retained/brought in so far seem to a) really fit the system and b) are probably too good for this level. You have to imagine that the likes of Hermansen, Winks, Fatawu, Mavididi, Coady, Vestergaard, Faes, Ricardo, Justin, KDH etc will all be playing very regularly - I trust that we will add smartly in January/over the summer too.
We're putting the cart before the horse a bit though - we're doing brilliantly, but we can't afford to start feeling like we've already made it. We're not up till we're up. Also, while I feel like we'll survive, I don't think we'll exactly thrive either, so we need to be prepared for a v different season if we go up IMO.
