It's that 13% variability that makes the game interesting - this is where managerial brilliance, coaching and tactics, team-dynamics - as well as just plain good or bad luck - come into play.
Important to note, though, that this is spend on wages - there's no proven relationship between transfer spend and league success.
Is there a comparison with higher scoring sports such as rugby, cricket, baseball basketball?
My assumption has always been that football is a low scoring sport which means that the impact of the 13% variability is all the greater. Shock results are much rarer in cricket and rugby.
Dirk's not quite correct - the observed relationship does change with 'era' and there's similar studies for other leagues. IIRC there's a follow up study that includes second tier and that's observed to be more random, which I think is at least qualitatively consistent. He's also not quite correct on 'no proven relationship' on transfers, there's some relationship, it's just much, much weaker (transfer spending explains
ca. 30 % of results, off the top of my head (and yes, the two numbers can add up to > 100% as they're not independent of each other)).
Anyway, popped by to say most of the analysis I've seen focuses on American sports, so look there for your answers.
