Andy Murray has insisted that he is not viewing his quest for Olympic gold in Rio de Janeiro as a defence of his victory at London 2012.
The Scot cruised into the second round of the tournament on Sunday as he defeated Viktor Troicki in straight sets in under 90 minutes.
Murray faces competition from the likes of Novak Djokovic and Rafael Nadal to claim silverware in Brazil but insists that he is viewing it as a fresh challenge.
"I am not defending a gold medal [from London 2012]; I will always keep my gold medal, that is always going to be there – I don't have to give it back," Murray told reporters.
"It is more trying to win another medal that builds the pressure and wanting to do something here – that is the pressure I am putting on myself.
"I am not thinking about what happened four years ago, it was an amazing experience for me, and having the Olympics coming so soon after Wimbledon, which was a big win for me, it would have been easy to have a lull and down time but that is not going to happen with the Olympics. It has worked out really well for me."
Murray now faces Juan Monaco of Argentina in the second round on Tuesday.
