Paris:Roger Federer's Wimbledon triumph on Sunday has seen him regain the world number one spot from arch-rival Rafael Nadal.
The Spaniard went top after last August's Beijing Olympics on the back of his win there and at Wimbledon in July.
He consolidated that by winning the Australian Open at the start of the year but lost to Robin Soderling in the fourth round of the French Open and then withdrew from the defence of his Wimbledon crown through injury.
