Stan Wawrinka has recruited Richard Krajicek to his coaching team ahead of Wimbledon later this month.
The world No 5 will be joined by Krajicek, a Wimbledon winner in 1996, when he warms up for the grass court season at London's Queen's Club next week.
Krajicek is added to Wawrinka's existing team, featuring coach Magnus Norman and assistant Yannick Fattebert.
Wawrinka announced on his Facebook page: "As I'm always looking to improve on court, I would like to take this opportunity to announce as of immediately that I have added Richard Krajicek to my existing coaching staff to help during the grass court season for the next four weeks.
"Adding a former Wimbledon champion can only further my knowledge and understanding of the grass. It's a real privilege and honour to add such a champion to my corner."
The Swiss player has become the latest player to hire the services of a former Grand Slam champion, following the recent announcement that Canadian Milos Raonic has linked up with three-time Wimbledon winner John McEnroe.
Wawrinka's compatriot Roger Federer previously worked with Swede Stefan Edberg, while world No 1 Novak Djokovic has Boris Becker, another former Wimbledon great, in his camp.
