Ivanovic’s career graph resembles that of another Anna, who also retired early: Anna Kournikova.
Russian Kournikova, who reached No 8 in the world and claimed two doubles Grand Slams alongside Martina Hingis, when injuries cut short her playing career in 2003, quit when she was just 21.
Ana Ivanovic caused a flutter in tennis circles by announcing her retirement at the age of 29 due to injuries, which had kept her out of action since August and dropped the Serbian to No 63 in the world rankings.
The Serbian spent 12 weeks as world No 1 in 2008 and won 15 singles titles in her career.
Although he has won three titles since Roland Garros, including two this year in Doha and Eastbourne.
