Not really the kind of question you would willingly put yourself forward to answer is it?
And, if for some strange reason you did willingly allow yourself to be called as a witness, it’s pretty much beyond comprehension that you would implicate yourself in behaviour that would see the highly lucrative career you have spent more than a decade building left in tatters.
(By the way, the same goes for any witness called in this tribunal, hence it’s an almost impossibly high bar for the panel to find against the club in any substantial way).
