Yes, it's not like bunging a doorman an extra fifty quid in a brown envelope, is it?
For the guys we are talking about it would need to be 100k a week to make it worthwhile. Maybe more. And it would have to be in cash, because any form of cheque or bank transfer would leave traces that can be detected by, among others, HMRC.
So this would involve obtaining around a million a week in cash, splitting it between the players (a suitcase each perhaps?) and them taking it away in their cars. I mean, no one would notice, would they? Who does the actual paying out? Khaldoon? Because if it's the equivalent of a wages clerk, that's an obvious security risk. A huge temptation to talk to someone about it.
Then the player gets his £100k home. What does he do with it? It can't be taken down to the bank, as again, the transaction would show. Anyone who pays in huge amounts of cash into a bank at regular intervals had better have a good explanation because someone is going to be asking questions. Heard of the Money Laundering Regulations?
Spend it? 100k a week? Really? You can't even put it on at Belle Vue Dogs these days. Shove it in a cupboard and leave it?
The sheer impracticality is obvious. What happens when someone leaves? Why would Jesus, for example, move to Arsenal and lose his £100k a week in readies? That's without thinking of the obvious legal issues.
