The possibility of complacency is the only thing we have to fear.
We are streets ahead of everyone in the league at the moment and will still be next season without any further additions. I worry about the complacency thing given how poorly we have at times performed against lower league opposition (Wolves, Bristol City, Wigan) and in dead rubbers (Basel, Shakhtar). I would love to see the fringe players really stepping it up a gear in these games and trying to force their way into the first 11 but we haven't seen that at all.
