Jamie Murray believes he and his brother Andy have their "best chance" of winning an Olympic gold medal as doubles at this summer's Games.
Despite Andy winning gold in the singles at London 2012, the pair have suffered early exits in the previous two Olympics.
But Jamie, who is now ranked top of the world doubles standings, is confident they can make a big impact in Rio.
"I am excited to go and play. It is going to be cool to play with Andy. London was a big disappointment for me personally," he told Sky Sports News.
"It is every four years, so to sit on that result for four years would be great. I really want to do well in this Olympics.
"It is probably our best chance to really get a good result because we are both getting to the peaks of our careers.
"I am certainly playing some of the best tennis of my life so I want to try to make that count."
The duo were part of the historic Great Britain team which won the Davis Cup for the first time since 1936 last year.
