The off-season coaching carousel is in full swing, with David Goffin and Madison Keys making changes to their teams.

Goffin, the top player from Belgium, announced that he will stop working with coaching consultant Thomas Johansson, who joined his team following the Australian Open.



"I would like to thank him for the good work we have done together this year, it's been a great experience," said Goffin.



Goffin is ranked a career-high No. 11 following a successful season that includes reaching the second week of the Australian Open, French Open and Wimbledon, along with semifinal appearances at Indian Wells and Miami. He did not win any titles, however, and hasn’t since 2014.

Goffin will continue working with his regular coach, Thierry Van Cleemput, who indicated to Belgian press that the 25-year-old had difficulty co-ordinating two coaches.



In a similar situation, OpenCourt.ca reports that Keys has stopped working with coach Thomas Hogstedt. The veteran WTA coach "helped her game a lot,” Open Court cited a source as saying, but there was "too big a personality conflict off the court.” Keys and Hogstedt began working together during the clay-court season.



Keys is at a career-high No. 8 in the rankings and qualified for the WTA Finals for the first time following a consistent, successful season in which she reached the final of Rome and won the title at Birmingham. The 21-year-old American has frequently changed her team—since former No. 1 Lindsay Davenport stopped coaching her a year ago because of family and other professional commitments, Keys has worked with Jesse Levine, Mats Wilander and Hogstedt, and is now apparently trialling another coach.
