This could be the greatest achievement of my career," Djokovic discusses a potential US Open title

Novak Djokovic has advanced to the quarterfinals of the US Open by defeating Jan-Lennard Struff. In reality, the Serbian only needs to win three more matches to lift the American Grand Slam trophy.

In a press conference, he commented on this possibility: "This could be the greatest achievement of my career, but it's still a long way off.

Over the past two years, I've learned to take things match by match, even though I dream of winning another Grand Slam. It would be incredible to do it here.

For now, I can't afford to think too much about it; I need to focus on what I have to do to win my next match, my next challenge.

My last Grand Slam was two years ago, so it would be nice to come full circle two years later.
