Andy Murray shares fan's hilarious post that claims tennis star 'will start rusting out in the rain' during Paris Olympics opening ceremony... as British legend gears up for final tournament of his career

Fans have hilariously warned Sir Andy Murray not to stay out in the rain of Paris' Olympic opening ceremony, as they fear he will rust. 

Murray shared a screenshot of one fan's sage advice on his Instagram, after he uploaded stories of him waving the Union Flag as Great Britain's flotilla sailed down Paris' Seine river.

The Scot kept a sunny disposition regardless, as he readies himself for his final tournament as a professional tennis player.

He announced on Tuesday that he was calling time on a heavily successful career as he arrived in Paris ahead of his fifth Olympic Games.

'Competing for Britain has been by far the most memorable weeks of my career and I'm extremely proud to get to do it one final time.'

Novak Djokovic is the latest of the sport's greats to pay tribute to the 'legend', Murray. 

Speaking on Thursday, Djokovic said: 'I heard the news about Andy and I hope that he will have the best possible farewell in his last competitive match in the Olympics, for him and his country.

'He is a legend of our sport and has been an incredibly important player for tennis globally. 

Djokovic also paid tribute to Rafa Nadal, who has similarly eluded to being in the twilight of his career, and said he hopes to still his old foe on the court in the future.

'Nadal of course the same,' the Serbian said. 'Even more all the results and achievements he has had, particularly in this city, in Roland Garros.

'Nadal didn't say when his last tournament will be, so hopefully for the sake of the sport he can keep going.'
