Two-time Grand Slam champion Andy Murray has called for the tennis governing bodies to pile more money into anti-doping measures.
The world of athletics has been hit with a fresh scandal as a WADA commission report recently alleged that doping is rife among Russian athletics.
It has also been alleged that bribes were made to the powers that be to allow some Russian athletes who feared doping bans to compete at the London 2012 Olympic Games.
Murray believes that the problem stretches to more sports than athletics, and that tennis needs to flood more money into their systems.
"I follow that stuff all the time," Murray told the Daily Mail. "What has happened with Russia is really bad, but I don't think it's just a Russia problem or just an athletics problem.
"It's up to the governing bodies just how much they want to tackle it because with the amount of money and profit sport actually makes, there needs to be enough spent on anti-doping.
"The prize money we have in tennis is extremely high and we need to look at how much we are spending on this area. I'm not an expert, I don't know what is enough and I don't know what other sports do, but in tennis we should be doing as much as we can."
It has been reported that tennis spends less than £3m a year on anti-doping measures.
