Renowned as one of tennis' greatest stars, Borg won 11 grand slam titles in the 1970s and early 80s, but in 'Heartbeats' the Swede lays bare the troubles that followed his decision to retire aged only 25.

As well as his successes on court, including the famous 1980 Wimbledon final against John McEnroe, Borg describes his battles with drugs and alcohol, as well as a turbulent personal life and business failures.
