Former world No 1 and French Open champion Ana Ivanovic has retired from tennis at the age of 29.

The Serbian made the announcement via Facebook on Wednesday night.

After her disappointing fifth-round exit from last August's US Open, Ivanovic revealed that she would be ending her season early to fully recover from a series of injuries that have hindered her in recent years.

Although she insisted at the time she would be returning to the sport, Ivanovic has now decided to bring her career to a close.

“There is no other way to say this. I have decided to retire from professional tennis. It was a difficult decision but there is so much to celebrate,” Ivanovic said on her Facebook page. “Don’t be sad, be optimistic alongside me. My love and my greatest thank you to all of you.

"By the time I was ranked No 1 in the world in 2008, I'd seen highs I've never dreamed of. I've won 15 WTA Tour singles titles, I played three Grand Slam titles and Fed Cup final.

"But seeing those 'highs' in any professional sport demands top physical form, and it is well known that I've been hampered by injuries.

"For myself, for my fans and for all the young girls and boys who might be watching me... I can only play if I can perform up to my own high standards, and I can no longer do that. It is time to move on.

"All I can say is that I've lived my dreams and I hope I've encouraged others to do so.

"To my family, management, sponsors and friends I thank you for everything."

Ivanovic’s future within the sport had come under question in recent years, with the Serb struggling to recreate the form that saw her secure her only Grand Slam title at the French Open in 2008.

After victory at Roland Garros, Ivanovic endured a prolonged period of reduced success, failing to make a Grand Slam quarter-final in her subsequent 15 major tournaments.

Her world ranking dropped as low as No 65 during the 2010 season and despite a resurgence in recent years – the Serb ended 2014 as No 5 in the world rankings – Ivanovic found herself back out of form.
