Roger Federer is one win away from becoming world No 1 for the first time in more than five years. Will the 20-time Grand Slam champion make more history?
The Swiss is through to the ABN AMRO World Tennis Tournament quarter-finals and a victory against Dutchman Robin Haase tonight would see the 36-year-old usurp Rafael Nadal at the top of the men's game.
Not only would it take him back to the top of the ATP Rankings for the first time in more than five years, but Federer would comfortably replace Andre Agassi as the oldest No 1. The American was 33 when he was last on top in September 2003.
Federer speaks about making his ATP breakthrough in Rotterdam when he had blonde streaks in his dark hair.
He was playing only the fourth ATP tournament of his career and had reached the quarter-finals of an ATP event for a second consecutive week. He was up against the reigning Australian Open champion Yevgeny Kafelnikov, but lost in three sets, 6-1 5-7 6-4.
Grigor Dimitrov, Alexander Zverev, David Goffin and compatriot Stan Wawrinka also speak about what a "special talent" Federer is.
"It would mean a lot to my team, my family, my fans; everybody who has been so supportive along the way. My comeback has been so incredible, but I thought I'd give it a go and see if I can get to world No 1 this week," said Federer.
