Andy Murray is one win away from becoming the world number one after he beat Tomas Berdych in straight sets in the quarter-finals at the Paris Masters.
Novak Djokovic had previously lost his quarter-final tie with Marin Cilic as the Serb was beaten by a scoreline of 4-6, 6-7, sending Cilic through to the semi-final stage of the competition.
It was the first time in a professional competition that the current number 1 seed had lost to the Croatian tennis ace after 14 previous victories, and the loss could not have come at a better time for Britain's Murray.
The quarter-final defeat for Djokovic means that, should Murray make it to the final of the competition, he will knock Djokovic off the top spot to become the new world number one ranked tennis player.
Murray has stated from the outset that his ultimate goal is to become the world number one, and now the British superstar is just one win away from realising that dream.
In the third round stage, Murray faced French pro Lucas Pouille but an unstoppable Murray proved to be just too much to handle for the Frenchman, with Murray winning in straight sets 6-3, 6-0.
The road to the number one spot for Murray now sees only one hurdle standing in his way.
He must beat either Jo-Wilfried Tsonga or Milos Raonic in the semis to reach the final, and with it the number one position.
The number 2 spot has kept a good solid grip on Murray, and since 2009, it has refused to let go.
Murray's lengthy occupation of the number 2 rank is a stat that will see him etch his name into the record books - should he reach the final - for the longest gap between reaching the number two spot and moving up to number one.
If Murray does succeed in his goal he will become the first player from Great Britain to reach the highly coveted number one spot in the world rankings since the time of British sports icon and fashion designer Fred Perry.
Perry first reached the world number 1 rank in 1934 and stayed there until 1937.
