I think Tone's point is that if they started doping at Barcelona they would show an improvement in being able to control a ball play accurate passes etc after 80+ minutes to use your example, they were however all world class players whose ability in those areas was top drawer at their old clubs already.
It's all highly speculative nonsense anyway, Barcelona are simply better than the rest. Not to say they aren't doping but they aren't using anything the competition isn't using too. Other clubs like Chelsea are much more suspicious in that regard, they played all competitions last year with what, 14 players, don't think I've ever seen anything like it. Oscar looks like he has no testosterone in his body and plays 60+ games a year for four or five seasons now, give me a break.
