Because I believe you can't suspend someone without pay unless it's a contractual part of the disciplinary process. And I doubt there are many contracts, and especially not for professional footballers, that would have that as a right for the employer. Far too open to abuse.
Plus it could maybe be seen as pre-judging an outcome.
So premier league footballer or not, he's as entitled to his salary as anyone else undergoing a criminal investigation or disciplinary action.
He's probably also missing out on a whole host of bonuses, so the £75kpw is probably less than that. (And yes, I realise how ridiculous that sounds!).
If that in anyway sounds as if I am defending him, I am absolutely not doing so. Scumbag of the highest (lowest?) order and I hope he gets everything he deserves.
But as in many cases, laws that are there to protect the many also benefit those on the extremes who may be less deserving.
