Britain’s Andy Murray is two wins from becoming world number one following Novak Djokovic’s surprise defeat by Marin Cilic at the Paris Masters.
Djokovic needed to reach the final to retain the top ranking but lost 6-4 7-6 (7-2) to Cilic in the quarter-finals.
Second seed Murray must beat Tomas Berdych and either Jo-Wilfried Tsonga or Milos Raonic to become world number one for the first time.
The Scot, 29, plays Czech seventh seed Berdych later on Friday.

Frenchman Tsonga then takes on Canada’s Raonic in the last of the quarter-finals.
Cilic had lost all 14 of his previous matches against Djokovic but made all the running in their 15th meeting, breaking serve twice in the first set and denying the top seed when he served for the second set.
Djokovic saw off two match points with a volley and a forehand winner but could not contain the more aggressive Cilic in the tie-break.
Murray is two wins from becoming the second-oldest player to debut at number one, after the 30-year-old John Newcombe in 1974.
The Wimbledon champion would also set a record for the most time between becoming number two and number one, having first reached number two in 2009.
