Andy Murray has hit out at the media, accusing the fourth estate of double standards.
Andy Murray is still aggrieved at his public treatment at last year's US Open.
The sixth seed coasted into the fourth round of the Australian Open at the expense of Joao Sousa 6-1 6-1 7-5 on Friday, but one of the talking points was Rafael Nadal's second-round victory on Wednesday.
Nadal battled physically in his five-set win over Tim Smyczek, and while the 14-time major winner was lauded for his bravery, Murray raised eyebrows after recalling the response to his battling predicament against Robin Haase in round one at Flushing Meadows.
"When I cramped and won in the us open last year I was a "drama Queen, unfit, needs to see a shrink, faker" weird..." Murray tweeted following the reaction to Nadal's win.
And on Friday, Murray said while he was not eager to vent his spleen, he took the opportunity to reveal what he felt was double standards.
"No, it wasn't something I've been itching to get off my chest at all," the two-time major winner said.
"I just remember what it was like for me when I came off the court at the US Open when I was in a lot of trouble, a lot of bother.
"It was very uncomfortable and quite painful. Some of the stuff that was said about me I thought was completely unfair.
"Yeah, the other night [when Nadal cramped and won] kind of proved it.
"I didn't watch the whole match the other night, but clearly Rafa was struggling pretty badly.
"It was a great effort to come through it, which rightly is what everyone was saying.
"But that certainly wasn't the case at the US Open when I was in a similar state. And I just don't understand why that would be the case."
Murray's next challenge in Melbourne will be facing 10th se+ed Grigor Dimitrov - with the chance for either player to take control of the bottom half of the draw following the exit of second seed Roger Federer.
Murray expects to be out on Rod Laver Arena on Sunday, and said his time playing on Hisense Arena prepares him appropriately for centre-court battles.
The British number one said: "I think for me Hisense and Rod Laver are quite similar. Margaret Court is quicker, in my opinion... slightly different conditions to Rod Laver and Hisense.
"Thought the atmosphere on Hisense today was great.
"From what people have been saying, the players have been saying, is I guess because it's such a big stadium and you don't need tickets to get in, you get all kind of the diehard fans.
"That made for a great atmosphere. I think with Roger losing, there's more of a chance we'll play on Laver."
