USA runner Bernard Lagat has said that he wants to upset the British crowd at London 2012 by beating home favourite Mo Farah.
The pair are expected to rival each other for gold in the 5000 metres event at this summer's Olympics.
Lagat is hoping to send a lot of fans home disappointed in the same manner as Roger Federer did with his Wimbledon victory over Andy Murray earlier this month.
He explained: "I'm going to have a few people cheering for me but I know it's going to be a big disappointment if he doesn't win - just like what we saw with Andy Murray against Roger Federer at Wimbledon.
"I'm sure a lot of people were disappointed and some of them were almost crying. There's always a lot of emotion when someone gets so close to winning something. The whole country will be cheering for Mo like they were cheering for Andy Murray, but guess what, he was beaten by Federer.
"And that's exactly what I want - to win. If I end up winning I know he'll congratulate me but he'll be very disappointed."
Lagat claimed gold and Farah finished fourth in 3000m final at the World Indoor Championships in March.
