The 18-times grand slam singles champion Martina Navratilova has quit as a part-time consultant to the world No9 Agnieszka Radwanska after just five months in the role.
The Pole hired Navratilova in December with the aim of reaching the latter stages of more big tournaments but the American great said she had been unable to dedicate enough time to the job.
“I am stepping down as Agnieszka’s part-time coach. I think I underestimated the time it would take to make this a good and proper situation for both Agnieszka and me,” the 58-year-old explained in a statement.
