World No.1 Novak Djokovic said tennis could be getting more money from legal betting activities than what was offered to him in 2007 to purposely lose a match, amid reports of match-fixing at the upper level of the sport.

Djokovic, who won Hyeon Chung of South Korea 6-3 6-2 6-4 in the first round of the 2016 Australian Open at Melbourne Park, did not take a hard stance in either direction when asked about the BBC and BuzzFeed reports about widespread match fixing at the upper level of the sport. But the Serb suggested there could be more money involved in legal betting activities than recent allegations about match fixing.

“You know, I know that there is also many betting companies that on the websites are using the names, the brands, images of tournaments and players and matches in order to profit from that,” Djokovic said, reports Tennis. “Tennis hasn't been really getting the piece of that cake, if you know what I mean.”

Controversial claims of match-fixing rocked the tennis world on Monday, but the more shocking revelation came from Djokovic, who admitted he was offered $200,000 to lose a first round match at a tournament in St. Petersburg, Russia. The Serb said he does not support such “crime in sport,” confessing that he felt “terrible” when he was offered to fix a tennis match.

Meanwhile, Roger Federer also joined the chorus of tennis players currently competing in this year’s Australian Open who reacted to the allegations that surfaced this week. The Swiss Maestro said he would love to hear the names on the list, which according to UK investigator Heidi Blake and BuzzFeed news reporter John Templon, includes more than 70 players suspected as fixers who have been flagged up to the tennis authorities over the past decade without being sanctioned.

"Hopefully there's more funding to it," Federer said, reports ESPN. "Same as doping. Yes, absolutely, got to be super aggressive in both areas."
