British number one Johanna Konta has reunited with her former coach Dimitri Zavialoff.
The partnership came to an end earlier this year with the Frenchman keen to reduce his amount of travelling.
He may not spend as much time on tour in future, with hitting partner Dan Smethurst still part of Konta's team.
Zavialoff was Stan Wawrinka's first coach, and also helped Swiss player Timea Bacsinszky break into the world's top 10 in 2016.
Konta had a trial with Maria Sharapova's former coach, Thomas Hogstedt, following her split from Zavialoff but that was not a success and she ended the season working with just Smethurst.
