Jamie Murray believes Olympic disappointment alongside his brother Andy sewed the seeds for his run to the US Open final.

The Murray brothers were one of the favourites to win doubles gold in Rio after their success together in the Davis Cup but they lost in the first round to Brazil's Thomaz Bellucci and Andre Sa.

While Andy Murray bounced back in Brazil to clinch gold in the singles, Jamie's revival has come at Flushing Meadows, where he is on the brink of a second grand slam title with partner Bruno Soares.

The duo are up against Spanish pair Pablo Carreno Busta and Guillermo Garcia-Lopez in Arthur Ashe Stadium on Saturday as they look to back up their maiden triumph, sealed at the Australian Open in January.

Murray admits failure at the Olympics sharpened his drive for success in New York, with his Canadian coach Louis Cayer offering some stern words of advice.

"It was obviously really disappointing with the result. It wasn't what I wanted and Louis was really annoyed after how it had gone for me," Murray said.

"He didn't say it to Bruno but he said to me: 'We're going to win the US Open. I'm going to do whatever it takes to win. We'll take it match by match, prepare for each match the best we can, and I really think you guys are going to do well'.

"It was just the fact that we had lost, just the way it had worked out. It was a huge event for us and he thought that we deserved better.

"He wants me to do the best that I possibly can. He was really disappointed with how the whole thing had gone. He felt the US Open in a couple of weeks was the right time to have a good tournament.

"We've been preparing for that each day and it's been going well so far."

Murray and Soares ousted the French pair and defending champions Nicolas Mahut and Pierre-Hugues Herbert on Thursday, who had beaten Murray in last year's final when he was partnered with Australian John Peers.

Their reward is a championship match against unseeded opponents, after Carreno Busta and Garcia-Lopez pulled off an upset of their own by knocking out their more fancied compatriots Feliciano Lopez and Marc Lopez.

Before this year's US Open, Carreno Busta and Garcia-Lopez had never gone past the quarter-finals of a major tournament and, speaking before the second semi-final had finished, Murray was open about whom he would rather face.

"I'd rather play Carreno Busta and Garcia-Lopez," Murray said.

Soares added: "The team that goes to the final, it's because they are doing a lot of things well. It's going to be a tough one no matter what.

"Everyone who has won five matches in this tournament is feeling good for sure and it's going to be a close match. We've got to perform our best."

Murray and Soares enjoyed enthusiastic support in the new Grandstand arena on Thursday but this weekend they will walk out to a rather emptier Arthur Ashe Stadium, with its 27,771 capacity.

Several players have been irritated this fortnight by the amount of noise and movement among spectators, and Murray took up the issue with umpire Marija Cicak during the semi-final.

Cicak was the same official who had so irked Andy Murray in the singles the day before, although Jamie insisted he was unaware of the coincidence.

"It was happening the whole match, people coming in when they call time," Murray said. "The people who are controlling the entrances don't close the gates so they keep letting people in.

"I don't care if they are up on the top level but if they're kind of in your eye-line then it's annoying."
