Andy Murray has achieved one of his biggest successes by reaching the world number one ranking.

Here, we look back at the most significant moments in his career.

US Open junior title (September 2004): Victory over Sergiy Stakhovsky at the age of 17 cemented his position as Britain's brightest hope.

First ATP Tour final (September 2005): Murray reached the final of the Thailand Open before losing to Roger Federer.

Maiden ATP Tour title (February 2006): Victory over Andy Roddick and Lleyton Hewitt gave Murray the title in San Jose and a place in the top 50.

Top-10 debut (April 2007): Murray breaks into the top 10 for the first time after reaching the semi-finals of the Masters events in Indian Wells and Miami.

US Open breakthrough (September 2008): Murray beat Rafael Nadal for the first time when they met in the semi-finals at Flushing Meadows. Federer was a class act in the final, however.

A grand slam title, at last (September 2012): Buoyed by Olympic success, Murray reached the final of the US Open. From two sets up against Novak Djokovic, he was pegged back, but the Scot found something extra and triumphed in five.

Wimbledon glory (July 2013): Murray survived a nerve-shredding last game to clinch a 6-4 7-5 6-4 win against world number one Djokovic to finally end Fred Perry's 77-year reign as the last home men's singles champion.

Davis Cup heroics (November 2015): Of all Murray's successes, guiding Britain to the Davis Cup title was the most unlikely. The Scot won 11 of Britain's 12 points, including three in doubles with brother Jamie.

Fifth Melbourne final (January 2016): Murray's search for an elusive Australian Open title goes on after his fourth final loss to Djokovic.

French Open final (June 2016): Having turned himself into one of the world's best clay-courters, Murray completed his set of slam finals by reaching the decider in Paris but the result was familiar - defeat by Djokovic.
