Andy Murray will place equal importance on both his Olympic tennis finals on Sunday as he goes for double gold at Wimbledon.
As well as facing Roger Federer in the singles final, Murray will also team up with Laura Robson in the mixed doubles. First they beat Australian duo Lleyton Hewitt and Sam Stosur 6-3 3-6 10-8 to reach the semi-finals, and then they beat Germans Christopher Kas and Sabine Lisicki 6-1 6-7 (9/7) 10-7.
Murray said: "For me, both matches are very important. I'd love to win two golds, and I'd obviously prefer one gold to two silvers. It's very different preparation to what I'm used to and that's the beauty of this competition."
He added: "Winning a mixed doubles title at Wimbledon would be great but winning the singles title is obviously much, much bigger, whereas here it counts for exactly the same in the medal table.
"I'd obviously love to beat Roger tomorrow as well but either match would be great to win and I'll give it my best in both."
Saturday's victories mean the worst Murray can come away with is two silver medals, while at 18 Robson will be the youngest Olympic tennis medallist since Jennifer Capriati won singles gold in Barcelona in 1992 aged 16.
It was not even decided Murray and Robson would play together until last weekend, and even then they needed a wild card to get in.
Robson said: "It's been an amazing week. I'm super excited for tomorrow and I'm sure we're going to do well."
Murray will look to follow in the footsteps of his brother Jamie, the Wimbledon mixed champion with Jelena Jankovic in 2007, in winning a mixed doubles title on Centre Court.
The Scot added: "It's been a great decision. I've enjoyed the whole week and to be guaranteed a couple of medals going into the last day is excellent. I wasn't expecting that, maybe in one but certainly not two."
