London: Bjorn Borg has predicted Roger Federer will retire at the end of next season.
Five-time Wimbledon champion Borg suspects the Swiss, who has 17 grand slam titles and is seeking more, will want to bow out at the top.
And a year that could see Federer go for gold at the Olympic Games in Brazil may offer that opportunity.
Borg said: "At 34 (Federer turns 34 in August) he still has the motivation, is still going out and working really hard - he wants to go out and win more tournaments and more grand slam tournaments.
"I think he's going to play one more year."
Speaking on Live@Wimbledon, the 59-year-old Swede added: "I think next year he wants to try to go for the Olympics in Rio, and then after next year I think he will step away from the game. I hope not."
Borg quit tennis in 1983 at the age of 26 after winning 11 grand slams, and a comeback in the early 1990s proved unsuccessful.
