The opening day of the Australian Open was overshadowed by reports in the BBC and online BuzzFeed News accusing tennis authorities of failing to deal with 16 players repeatedly flagged up to the Tennis Integrity Unit (TIU) over suspicions of matches being thrown.
Both Federer and defending champion Djokovic strolled through their opening matches in Melbourne, but were inevitably asked about the story rocking the sport.
"I would like to hear the names," 34-year-old Federer told reporters when asked to comment on claims that grand slam champions were among the players involved and that eight of them were playing in the Australian Open.
"I would love to hear names. Then at least it's concrete stuff and you can actually debate about it."
