You can't knock the job he's done, however like many promoted teams over the years...the toughest job now is transitioning and being able to cope with inevitable setbacks in the Premier League.
But getting out of the Championship as clear winners is a big achievement, especially when you consider the massive changes in players without dipping into a budget, but actually turning a profit in sales/purchases.
In terms of points and the gap, only Wolves and Leicester are comparable and they've both had good runs as PL clubs so the Burnley stigma could be about to change.
