World number one Iga Swiatek says she is "very excited" to get to work with Wim Fissette after appointing the Belgian as her new coach.

Swiatek, 23, parted ways with Tomasz Wiktorowski earlier this month after three seasons together with the Pole.

Fissette, 44, has worked with former Grand Slam winners Kim Clijsters and Angelique Kerber during his coaching career.

He split with Japan's Naomi Osaka in September, having helped the 26-year-old to two of her four Grand Slam titles.

"I want to say that Im very excited and looking forward to working with Wim," Swiatek said on Instagram.

"I'm preparing for the WTA Finals but my perspective is, as always, long term, not short term.

"I said many times that my career is a marathon, not a sprint, and I'm working, operating and making decisions with this approach."

Swiatek added that Fissette "seems to have a great attitude, vision and huge experience at the very top level of tennis".

The Pole's split with Wiktorowski came after winning four of her five Grand Slams with the 43-year-old - including this year's French Open.

However, she was unhappy with her hard court performances this season and felt the time was right for a change.
