Drugs in SportThe doctor at the centre of the Spanish doping investigation has said he treated footballers, athletes and tennis players as well as cyclists. However, Dr Eufemiano Fuentes denied his methods could be classed as doping.

Fuentes's declarations come in stark contrast to a statement released by the Spanish government on Tuesday that said no footballers or tennis players were implicated.

"Names have appeared of people that I don't even know and there are others that haven't come out and I've no idea why but my professional oath forbids me from revealing their names.

"Treatment only for cyclists? I'm also indignant about that. I've worked with other sports, like athletics, tennis and football. There are a lot of names that haven't come out, there has been only selective leaks. I don't know why."
