I find the notion of individual players doing it to be perfectly plausible, but a whole squad? That's got too many variables in it for things to almost inevitably unravel very quickly. Fall outs (over money or team selection) followed by blackmail and extortion and what about those players who simply said 'no'. It's hard to imagine a whole squad of 25 going along with something with serious question marks about its long term health effects, which would impact on their future earning potential and reputation in the likely event it was eventfully exposed. Like pretty much any conspiracy it would only be as strong as the weakest link.
I'm inclined, on balance, to say no, not because of any faith in human nature, or any lack of cynicism on my part, but because of the practicalities involved in such an arrangement and the overriding capacity for it to fuck up royally.
Many thought the same about Armstrong; that he was a lone wolf, yet it later transpired that virtually the whole of the US Postal team were “in”. And this was replicated right throughout the peloton as whole teams were "super-charged". Very few professionals opted out (it meant getting left behind from the gun, which meant no wins and no wages). And those that did ever speak out were, to use the cycling vernacular, accused of “spitting in the soup” and were essentialy quietened with little public outcry. The law of omerta was massive; nobody spoke out.
EPO was and still is to a smaller degree, the curse of competitive cycling. When micro-dosed, it’s very, very difficult to detect. Whilst it wouldn’t give a player bionic powers, super speed, what it does do, is allow a sportsman to train. And train. And train. With very little impact, ie normally a player would need to ally their training with the usual sleep/rest. EPO allows the human body to become almost impervious to the fatigue normally associated with top-class sport. It’s why it became so popular in cycling, one of, if not the ultimate endurance sport, where fatigue is a constant companion, especially in the 3 week grand tours (the pinnacle of the sport).
Would it surprise me to see it being used in top-flight football? Absolutely not. I’d be more surprised if it weren’t being used. It ticks a lot of boxes:
Easy to get hold of
Hard to detect
Positive impact on performance without raising too many eyebrows (a la Ben Johnson 100m run)
Negligible/no long term effects
Don’t think it’s a hard thing to arrange GDM. It isn’t. And wasn’t for the hundreds of cyclists who systematically used it. Daily. For years. I’ll hazard this is the opening salvo in a debate that will run and run (pardon the pun).
