With a second Wimbledon title in the bag, a second Olympics gold medal in his pocket and his biggest rival struggling with injury, Andy Murray believes he has a golden chance to add to his three grand slam titles.

The second-ranked Scot, who has lost just twice since early May, is favoured by some to dethrone an ailing Novak Djokovic this week and win a second US Open title, though the Serbian top seed remains the favourite with bookmakers.

At 29, Murray knows that his time at the top is limited and is setting his sights on winning more grand slam titles, sooner rather than later.

“I would imagine if I’m lucky I’d be playing at this level for three, four more years, max, I would think,” said 2012 champion Murray.

“So, I want to make the most of every tournament I play in and try and win and achieve as much as I can the next few years.”

Murray could hardly have arrived in better form, having won four titles this year, all of them since May.

A reunion with his coach Ivan Lendl in June sparked immediate results with victory at Wimbledon.

He begins his US Open challenge tomorrow against Lukas Rosol, the Czech who beat Rafa Nadal at Wimbledon in 2012.

After a quick turnaround from Rio to Cincinnati, where he reached the final before losing to Marin Cilic, Murray took a couple of days off to rest and told reporters some minor shoulder soreness was no longer an issue.
