WTA Tour: Agnieszka Radwanska 'overjoyed' to welcome Martina Navratilova to her coaching team

Agnieszka Radwanska says she is 'delighted' Martina Navratilova has agreed to become part of her coaching team.

The 25-year-old Pole, currently ranked sixth in the world, is hoping the appointment of one of the game's all-time greats will help her secure a first Grand Slam title.

Navratilova, 58, won 18 Grand Slam singles titles herself between 1978 and 1990, and also spent 332 weeks as world No 1.

Radwanska said: "I am absolutely delighted Martina has agreed to help me and my team next season.

"She is my idol in tennis and I am honoured we will be working together. Her achievements speak for themselves and I hope that I can learn from all her experience.

"My goal is to win a Grand Slam, so to have someone with Martina's accomplishments in my corner is going to be hugely advantageous and give me a big boost."

The closest Radwanska has come to winning a Grand Slam was in 2012 when she reached the Wimbledon final only to lose in three sets to Serena Williams.

Tomasz Wiktorowski will remain Radwanska’s main coach but nine-time Wimbledon champion Navratilova admits she is just looking forward to a return to the day-to-day involvement in the sport.

I did not sleep very well last night.

"I did not sleep very well last night, thinking about getting back into match mode and the competitions," she said.

"I am really excited about this opportunity to join Agnieszka's team and work with Tomasz and it is going to be a fun challenge."
