(CNN) -- If Muhammad Ali, Pele, Tiger Woods, Michael Schumacher and Michael Jordan are arguably the greatest proponents of their respective sports, Roger Federer made a compelling case for joining that pantheon of greats after securing a record-equaling seventh Wimbledon title on Sunday. At the age of 30, considered a grand old age in tennis, he came from behind to leave Andy Murray -- an opponent five years his junior -- shattered and tearful after a gripping three and a half hours on Centre Court. It ended Federer's two-and-a-half-year wait for a record-extending 17th grand slam title, and equaled his hero Pete Sampras' seven successes at the All England Club.
