Following are the six men to win all four grand slam titles after Roger Federer won his first French Open on Sunday to add his name to the list:
Fred Perry (Britain)
* Completed the clean sweep in 1935 at the French Open, his fifth title, and went on to win eight in all.
Don Budge (U.S.)
* Perry's great rival of the 1930s, Budge took just three years to emulate the Briton's multi-surface achievement, also at the French Open.
Rod Laver (Australia)
* One of the true greats of the sport, he won the grand slam (all four titles in one year) in 1962 and 1969.
Roy Emerson (Australia)
* Like Budge, Emerson did not wait long to emulate his rival by clinching the 1964 Wimbledon title.
Andre Agassi (U.S.)
* Over thirty years passed before Agassi, in 1999, became the fifth man to win all four.
Roger Federer (Switzerland)
* Federer could have joined the list as early as 2006, when having won the other three grand slam titles he first appeared in a French Open final. Also finished runner-up at Roland Garros in 2007 and 2008.
