Former Wimbledon champion Goran Ivanisevic says Marion Bartoli will regret her decision to retire from tennis.

The 28-year-old Frenchwoman made the shock announcement after losing to Simona Halep in the second round of the Western & Southern Open in Cincinnati, saying injuries have taken their toll.

Bartoli's decision comes only 40 days after she achieved her dream of winning Wimbledon with a straight-sets defeat of Sabine Lisicki. Ivanisevic said: "What she did at Wimbledon was fantastic but she will regret this decision when Wimbledon comes.

"There is nothing like playing at Wimbledon as Wimbledon champion."

Former French player Guy Forget worries Bartoli has made a rash decision and has urged her to take time to think it through.

He said: "I'm always very cautious about someone's quote right after a defeat.

"I hope she is going to change her mind."
