Andy Murray has revealed that his perseverance was key to his victory over Adrian Mannarino in the second round of the US Open.
The British number one was forced to come from two sets down after he spurned several chances to break the 27-year-old, but he was able to rally to clinch his place in the third round of the competition.
When asked about the key to his comeback, Murray told reporters: "You need to believe for a start, which is not always easy. I obviously had quite a few opportunities, I think I was one for seven on break points.
"In the first set I had 0-40 at 6-5 on his serve and I just was not able to break him at any of the important moments unfortunately.
"I just had to tell myself that I would get there eventually and managed to turn it around."
The world number three will play Thomaz Bellucci in the third round.
