The claim, made by rising Greek star Stefanos Tsitsipas, is that Federer and other top stars benefit from privileges from match officials.
Tsitsipas first made the accusation on court when frustration boiled after what he perceived to be a late challenge from legendary pairing the Bryan brothers in the Miami Open men’s doubles final, and he referenced Federer as one of the recipients of preferential treatment.
The Athenian didn’t stop there, though, and defended his outburst during a Twitter Q&A moments before Federer’s singles final against big-serving American John Isner.
He tweeted: I think players that have been doing really well over the years, players that are generally much respected in the tennis world, have privileges when it comes to certain rules and umpire decisions.
I felt this a couple of times when playing these guys and I think it’s a bit unfair.
Tsitsipas holds no ill-feeling towards his idol Federer over the situation, believing the Swiss is blame-free. Roger Federer is always going to be my favourite player no matter what,’ he added.
I don’t want to drag him into this. It’s not his fault or intention, it’s the umpires that are trying to protect them more than they are supposed to. Nothing more than that.
