Iga Swiatek: WTA number one splits with coach Tomasz Wiktorowski after three years

Russell Fuller, BBC tennis correspondent:

Swiatek says a chance to spend more time at home after three years of travelling will be welcome to Wiktorowski, and also indicates this is the right time for her to start working with a non-Polish coach.

Piotr Sierzputowski guided her through the majority of her teenage years, with Swiatek suggesting in the past that she has been more comfortable being surrounded by people with whom she shares a language and a culture.

It is, unusually, now four months since the world number one won a title. She has not played since losing to Jessica Pegula in the US Open quarter-finals, missed this week’s China Open for personal reasons and will not play next week in Wuhan either “after an important change in my team”.

Swiatek has frequently criticised the relentless nature of the circuit and the increase in mandatory tournaments on the WTA Tour.

She has already decided not to represent Poland in the Billie Jean King Cup Finals – which leaves next month’s WTA Finals as perhaps her only appearance before the year is out.
