Wimbledon champion Iga Swiatek has hired Francisco Roig, who was part of Rafael Nadal's team and later coached Emma Raducanu, after the Polish world number four ended her coaching partnership with Wim Fissette last month.

The six-time Grand Slam winner split with Fissette after a 17-month stint following a shock early exit at the Miami Open with a loss to world number 50 Magda Linette.

"Welcome to the team, Francisco! Very excited for this new chapter," Swiatek wrote in an Instagram story on Thursday. Spaniard Roig was part of Nadal's team for 16 Grand Slam wins, but his stint as Raducanu's coach lasted only six months as the Briton struggled to regain her form.

Swiatek has also struggled this year, facing quarter-final exits from the Australian Open, Qatar Open and Indian Wells before the loss in Miami.

The 24-year-old will be gunning for her fifth French Open title when the second Grand Slam of the year starts next month.
