Logic says some of them probably do, must be a temptation for all footballers. Do I think we have a club orchestrated sophisticated doping campaign? If we do we must be carrying it out very badly (although that wouldn’t be a shock either). We’ve been consistently awful for ages with very few unusual periods of form or performances over the norm, our players are utterly injury prone, and most of our players are blowing after about ten minutes (that’s if they’ve bothered running), so if we are doping then our players must actually be absolutely awful (actually I could buy that as well).
It would be hard for any club to orchestrate a doping campaign as we all have squads from different parts of the world who have different beliefs and religions they follow.
Not everyone is going to agree and would feel disgusted at the suggestion to some people.
Same for the coaching staff.
