Another former Grand Slam champion is set to make a comeback in 2018.

France's Marion Bartoli, the 2013 Wimbledon champion, announced her return to WTA tennis via a video posted to social media on Tuesday.

"I have something to tell you -- I'm coming back this year on the professional tour!" Bartoli told fans.

"It's going to be a huge challenge; I still have a lot of practice ahead of me, but I'm hoping to be ready for March and the Miami Open."

The Frenchwoman added: "I'm really looking forward to be on the court again in front of you, to feel your support, especially in Paris, in Roland Garros, in my home country, but also for the Fed Cup - and Wimbledon. I'm so looking forward to it."

The Frenchwoman last played a competitive match on the WTA four years ago, when she fell to Simona Halep at the Western & Southern Open in Cincinnati.

She announced her immediate retirement from the sport after that defeat, just over a month after winning her first Grand Slam title.

Since then, she has worked as a commentator for Eurosport, among other ventures. 

Bartoli peaked at a career-high of World No.7 in 2012, and also reached the Wimbledon final in 2007. She ended the year inside the world's Top 20 for eight straight seasons from 2006 through 2013.
