On the back of storming into this year's US Open quarter-final, Roger Federer looked back on previous encounters between himself and Argentine Juan Martin del Potro, citing his 2009 classic as a match he would want to have another go at.
"I'm not sure. I felt like that I left that match with a lot of regrets. Probably feels like one of those matches I would like to play over again. Feel like I would probably win it," said Federer.
Back in 2009, Del Potro, aged at only 20, shocked the world of tennis with a pulsating win over then five-year reigning US Open champion Roger Federer.
It was at this point that Del Potro announced himself on one of the biggest stages in tennis, and it seems as though Federer has never really got his head round how he managed to end up on the receiving end of that upset.
"I just had all these chances in multiple moments. The only time when he was really better, in my opinion, was the fifth set. Obviously that was good enough to beat me that day. It was a good match. A lot of back and forth."
Although this may come across to some as a slightly bitter tone for the Swiss sensation to have, he acknowledges that it was an "epic", with his respect and admiration for Del Potro elevated tenfold after his monumental triumph.
Following on from this, in anticipation of their mouthwatering clash on September 10, Federer stated that he hopes they can reproduce the quality of that famed '09 final, but quickly addresses that it will be a very different game in comparison to previous iterations.
"I play shorter points. I don't use my slice as much, whereas he does now. It's a bit of a change. We did play each other in Miami, so I did get a sense of how it is to play him now. "
In Federer's closing lines, he tries to play down the importance of the occasion, admitting that in comparison to 2009, this matchup will probably not have the same intensity.
"I think we're both more laid back today. It won't be a final, it will be a quarter final. Obviously not as much riding on this match like it was in 2009."
His comments may well be seen as a ploy from the legendary figure of tennis to try and avoid any potential embarrassment should he suffer another defeat by the hands of the now seasoned Argentine.
