Djokovic calls for more testing tennis

World number one Novak Djokovic yesterday claimed he is currently providing fewer blood samples for drug testing than he was two years ago — but insists tennis need not fear a Lance Armstrong-style doping scandal.

Armstrong’s long-awaited interview with Oprah Winfrey, in which he admitted taking performance-enhancing drugs over much of his career despite repeated denials, was aired overnight.

And after ripping into the shamed American cyclist — Djokovic said Armstrong “should suffer for his lies” — the Serbian, a five-time grand slam champion, believes tennis’ procedures are sufficient.
