His goal record last 4 seasons: 18, 17, 25, 16. There are no guarantees in football but that he will score goals is as close as you'll get.
Including seasons in the championship to pad his stats
He's had one good year in the PL, there is absolutely no guarantee he'd be a success for us especially considering we have struggled to create chances for a fucking decade.
Whereas QPR last season created between 20-25 golden chances per game I suppose?
