Andy Murray in peak sort before US Open while doubts linger over Novak Djokovic | Kevin Mitchell

While doubts over Novak Djokovics fitness remain, Andy Murray is focused on his route to a fourth Grand Slam final of the year and chance to clinch a second US Open crown

Andy Murray is right to point out that doubts over Novak Djokovics fitness leaving aside the Serbs revelation that his private life has been in turmoil will have no effect on his own progress through the depict at this US Open.

However, while the two best players in the world are not scheduled to meet until the final, Murray knows, but dare not utter too loudly, that Djokovic is more vulnerable than “hes having” been at any major over the past few years and his elimination would induce his grab for a second major this year far easier.

Although he would savour current challenges, there is nobody Murray would less like to play if he were to emerge triumphant than the man who has beaten him 24 periods out of 34, including 15 from 19 since the Scot won the final here against him four years ago.

As for Djokovics troublesome wrist, Murray watches it this style: Ive had a long summer as well. My body is not fresh and my body is not perfect either. Ive played a lot.

Often its been the case at the US Open that guys at this stage of this year are fatigued, especially ones who have been vying for the majors throughout the year. This year is the same and we will see on Monday if Novaks wrist is fine. I am sure he wouldnt be risking it if it was bad.

Also, he is coming in fresh because he has not played loadings the last few weeks. My advantage is that I have played a lot of matches and am coming in with the confidence of that knowing that physically I am in good shape. I dont see this as any more of an opportunity than any of the other slams.

However, if the world No1 were to fight in his opening match against Jerzy Janowicz on Monday because of his injured left wrist, there is a distinct prospect he would consider withdrawing from the tournament. After the draw on Friday, he did not exactly ooze confidence.

Djokovic, who has dipped from his normally stratospheric level since going out in the third round at Wimbledon, knows he is the obvious target for several desperate carnivores on his side of the describe, chiefly Rafael Nadal and the Wimbledon finalist, Milos Raonic.
