Well, the two aren't mutually exclusive. The particular allegations were bullshit. But as you say, that doesn't mean we didn't do something else.This is why I've never held much credence to the Der Spiegel/ UEFA charges.
If any club truly wanted to bypass UEFA's rules, rather than doing it in a way which, if discovered, would leave them open to sanctions, there are many many ways of achieving that, without doing something piss obvious.
