Björn Borg Lost 'Motivation' Before Early Retirement
Björn Borg won eight Grand Slam titles throughout his tennis career.
Borg is set to dive deep in his memoir.
During a rare interview with The Athletic last year, Borg opened up about what led to his shockingly early retirement at age 26 in 1983.
The tennis star said he was "very happy as a player, but the motivation was not there."
Björn Borg had an early retirement from the sport of tennis.
"If you don’t have the motivation to practice and compete every day, you can’t focus on what you do and what you need to do. I was happy, but I had no motivation and no focus. When I came back briefly, that was a different story. I’m writing a book. I’m going to tell everyone all about it next year," he explained at the time.
Amid his retirement, Borg played in one tournament in 1983 and another the following year.
After his brief hiatus, the world champion returned to the sport in 1991 for three more years — but never again won a tennis title.
