London (CNN) -- In a career already groaning under the weight of titles and accolades, Roger Federer joined another exclusive list of tennis luminaries when he beat Andy Murray in this year's Wimbledon final. In notching up his seventh Wimbledon win a month before his 31st birthday, Federer became the oldest champion since Arthur Ashe in 1975, and only the 11th player in the Open era to win a grand slam in his 30s. Only Andre Agassi (at the Australian Open in 2001 and 2003) and Pete Sampras (U.S. Open 2002) have achieved the feat this century suggesting that, more than ever, modern tennis is a game which favors the power, agility and the sheer exuberance of youth.
