I found this passage way more interesting:
Roger Federer and Andy Murray ask more blood controls to make sure that tennis is clean:” I follow what the chiefs of ATP decide. I’m fine because Rafa is clean, it’s impossible to dope in tennis. If ATP thinks that is right to increase anti- doping controls, do what they think it’s better. It’s true that there was the case of Mariano Puerta, but since then no top tennis player has ever doped, I think that they are all clean. It’s hard to dope.”
I'm not sure what his aim was with this. Clearly, players have and are doping after Puerta (Odesnik).
