Double Paralympic champion Jonnie Peacock is hoping to renew his rivalry with Richard Browne at World Para Athletics Championships London 2017 later this summer.
The pair are familiar foes after battling in the T44 100m over recent years, with Browne the current defending world champion after claiming gold in Doha two years ago.
But Peacock has doubts over whether the American will turn up at London Stadium
"I was meant to race Richard at the Manchester Paralympic World Cup, I was informed by the organiser a day before the race that he hadn’t got on his plane, he hadn’t told anyone he didn’t get on his plane," he said.
"I don’t know what happened there - personally from my perspective that’s just plain rude. That was disappointing because I was very much looking forward to that race.
"I don't think he will be there [in London]. I hope he is."
And looking ahead to July when the World Para Athletics Championships take place, Briton Peacock has a firm message for his rival.
"I hope you're there. You're the defending champion, anything can happen in a final and you’ve got nothing to lose so stand there. I’d love to race you."
