London - Andy Murray has joined Rafael Nadal in attacking the intrusive methods now in effect to try and catch dope cheats in world sport.

The Scot said he's not pleased at having to tell international drugs enforcers his whereabouts for one hour per day, every day on the calendar. The rule came into effect on January 1 and is fully backed by the ATP despite rumblings from many players.

The lightning raids being carried out under the direction of anti-doping body WADA carry strict sanctions: three failures to be in place for surprise tests over an 18-month can result in punishment including suspensions of up to two years.

Nadal has already branded the system unworkable and voiced his displeasure. Roger Federer sees it as a necessary evil, though he is hardly pleased to submit to such a regime.

"These new rules are so draconian that it makes it almost impossible to live a normal life," Murray told London's Times. "I got a visit at 7 am one morning at my home right after I had travelled home from Australia (2008).

"I woke up not really knowing where I was and suffering badly from jet lag. It seemed ridiculous to me as I'd been tested just four days earlier, straight after the match I had lost in the Australian Open.

"The official who came to my home wanted me to produce identification to prove who I was. He insisted on watching me provide a sample, literally with my trousers round my ankles, and then insisted that I wrote down my own address, even though he was at my private home at 7 am.

"Tennis has not got a big problem with drugs. I support drug testing and strongly condemn any use of drugs in sport, but there has to be a more realistic and practical way to deal with the problem with tennis players." (dpa)
