DO YOU REMEMBER -- MONICA SELES

Former world number one Monica Seles has announced her official retirement from tennis.

The 34-year-old won nine Grand Slam singles titles in her career, but has not played competitively since June 2003 because of a foot injury.

Seles won her first Grand Slam title in 1990 at the age of just 17 and topped the world rankings the following year.

In a horrifying event in April 1993 she was stabbed on court in Germany and spent 28 months away from the sport.

After returning in 1995 Seles managed to win one final Grand Slam title, the Australian Open in 1996, finishing with a major haul of four Australian, three French and two US Open titles.
