I mean it's not a high risk prediction anyway. Most teams don't.
But I'd imagine if Liverpool are doing, then we probably are as well. I remember when I used to do judo as a kid, Red Bull wasn't allowed. But then they invested shitloads into sport and suddenly the rules were changed in most sports. Caffeine used to be banned in most sports and now it isn't. And in the modern era of sports science, if something beneficial is allowed, no-one is not going to be doing it.
TUEs are a very dodgy area, because presumably it's against the rules to lie about having a condition you don't have, but then a lot of diagnoses are given by a single doctor, who can presumably be the one employed by the club. It'd be interesting if TUEs required a second opinion from an independent doctor. Maybe it does, I don't know.
Is there any independent verification of this 63% asthmatic claim btw, because I've only read it on a few blogs. Is there a place where TUEs are publicly available, or would that be considered a breach of patient confidentiality?
