Swiatek asked which player she would choose as coach: "Petkovic or Sabalenka".

Iga Swiatek qualified for the quarter-finals of the WTA 1000 tournament in Dubai by beating Dayana Yastremska.

At the press conference, a journalist asked her which player she would choose as coach, in the manner of Novak Djokovic and Andy Murray.

She replied: "Andrea Petkovic doesn't play anymore, but I've heard she has a good eye. I've always liked her, so I think we'd get on well.

Or maybe Aryna Sabalenka. She's older than me, so maybe she'll retire sooner than me. That would be fun."

Swiatek will face Mirra Andreeva in the quarter-finals.
