I agree, but it's a huge number of players that will quickly become unhappy when they're spending more time out of the squad than on the pitch. The manager then also has to find a way of getting his team to work cohesively which he may stumble on accidentally like Chelsea did, or not at all.
While I think it's total bullshit that effing Wrexham can get so much from some Hollywood faces pulling in favours and just wish they'd piss off, it means they're in no danger of falling foul of the rules. Birmingham however it seems much shadier. If the American Tommy Shelby wannabe doesn't get what he wants property wise I think he'll leave them high and dry.
