About Bjorn Borg:
Björn Borg is a former world No. 1 tennis player from Sweden widely considered to be one of the greatest in tennis history. Between 1974 and 1981 he became the first male professional to win 11 Grand Slam singles titles: six at the French Open and five consecutive at Wimbledon. He also won three year-end championships and 15 Grand Prix Super Series titles.
My greatest point is my persistence. I never give up in a match. However down I am, I fight until the last ball. My list of matches shows that I have turned a great many so-called irretrievable defeats into victories.Bjorn Borg
You never know how long Federer is going to play, but in my opinion he has at least one or two more grand slams to win. It depends how long he stays motivated. For me, he is the greatest player to ever play the game.Bjorn Borg
