Two articles on doping; the second is mostly about US sports but is a superb read.

It's difficult to maintain an interest in football these days - it's just so unbelievably corrupt.
Hand on heart I can't say I don't think some of my favourite Arsenal memories are influenced by doped players. Perhaps less than at other clubs given who our manager is, but there are players who I really have doubts about.
