Well, firstly, that's a bizarre false equivalence. Paying a footballer high wages is not equivalent to becoming the PR plaything of a dictatorial and human rights-abusing belligerent regime.
And I would argue that the only thing "immoral" about paying the actual workers (the footballers) high wages is the fact that fans fund those wages via high ticket prices and television fees (which we have a choice not to pay). I would rather see higher wages go to the footballers than my ticket money go straight to the owners' pockets.
Secondly, you're wrong about there being no morality in football. Our very own Juan Mata started an admirable charity which advocates the consistant and ongoing donation of wages to charitable causes, for example. And Manchester United, for all our sins, are heavily active in the community. These are examples of morality existing in football. That won't all stop if we get bought by Saudi Arabia. But it would be a big step in the wrong direction.
