I have many reasons for not liking guardiola.
Doping isn't one of them, in fact I'm surprised at the conspiracy theorists. Firstly, doping in football is not as beneficial as individual sports, unless of course an entire team is doping. In this day and age with so many transfers, so many bitter departures of players and so on, I don't even see how it would be feasible. Within national teams possibly, but at elite club level, barring individual players doing it, I do not see how a systematic club approach would even work.
