I was looking at his stats, in the 4 seasons came from Fleetwood he's had 2 in the Championship and 2 in the Premier League.
In each pair he's not scored many in the 1st of those two and then done quite well in the 2nd - particularly last year of course.
So there is cause to think that on both occasions he's taken a season to bed in and get used to the new level and then done better the following year.
I still think last year was probably his annus mirabilis and he's unlikely to repeat it, but I don't think he'll be a complete flop next year wherever he is.
