Federer returned to world No 1 last Friday, beating Robin Haase in the quarter-final of the Rotterdam Open. More than 14years after Federer first reached No. 1, swissinfo.ch looks at the complete history of all the top-ranked maleplayers in one graphic.
Playing flawless tennis, the 20-times major victor carried the momentum forward in the second set to seal the match in 55 minutes for his 97th career title and third in Rotterdam.
The Swiss, who earlier this week confirmed his return to the top of the ATP world rankings, breezed past Dimitrov 6-2 6-2 on the way to his 97th tour-level trophy.
Bedene, who has reverted to competing for Slovenia, was beaten 6-2 6-4 in one hour and 31 minutes by the 24-year-old Austrian. I would like to thank everybody who has been part of this tournament over the years.
Acknowledging Federer becoming the new World No 1, his WTA counterpart Caroline Wozniacki said: "Roger is such an incredible athlete and obviously a great champion".
Many regard Federer as one of the sport's greatest ever, while Nadal's 10 French Open victories have seen him become known as 'The King of Clay.' But Agassi, who today saw his record of being the oldest No 1 ever eclipsed by Federer, reckons Kyrgios has the talent to rival anyone.
Federer has a home and training base in the UAE and has won the hardcourt tournament seven times. He took a six-month sabbatical over the last half of 2016 to allow his surgically repaired left knee to heal fully.
"Thank you very very much".
"It just shows if you have a staying power, and you have a pleasing style and you treat people right along the way, including the press, which I think is important, there's a lot to be learned from his journey", Clarey said while on The Tennis Podcast. And I asked them how long since he was No 1 in the world.
