Glasgow-born Sir Andy Murray is widely considered to be the greatest British men's tennis player in history, with his 46 singles titles placing him at 14th on the world all-time list.
Despite playing at the same time as three of the most talented players the sport has ever seen - in Novak Djokovic, Roger Federer and Rafael Nadal - Murray has still managed to win his fair share of games, and finals, against the trio.
He's been world number one of 41, finishing 2016 in top spot, and has managed to convert 11 grand slam final appearances into three wins - one at the US Open and two at Wimbledon.
There's also the small matter of winning back-to-back singles gold medals at the Olympic Games in London and Rio de Janeiro.
And it will be at the Olympics that he will make his professional swansong, posting onto social media that he has arrived in Paris for his “last ever tennis tournament”.
But there have been plenty of highs for his fans to enjoy in previous years.
Here's a trip through Murray's career - via all 46 of his ranking singles wins.
