Melbourne - Andy Murray thinks its "hypocritical" that tennis tournaments are sponsored by betting companies as the sport tries to combat match-fixing.
A day after reports by BBC and BuzzFeed alleged that tennis authorities were suppressing evidence of match-fixing at the sport's highest level, Murray said he didn't agree with the fact the Australian Open is being sponsored this year by a London-based betting agency.
"I think it's a little bit hypocritical, really," he said. "You know, because I don't believe the players are allowed to be sponsored by betting companies but then the tournaments are. I don't really understand how it all works. I think it's a bit strange."
Murray also said the tours should do a better job educating players - especially younger ones - what to do in case they are approached by match fixers.
"You have to be proactive I think with things like this and go and speak to the players rather than them reading about it in the newspapers or, you know, listening to it on the TV or the radio," he said.
"Because I know when I was growing up - I mean, certainly throughout my whole career - I was never warned about that or told about that or anyone said to me how you should handle that if you're in that situation."
