World number five Stan Wawrinka has announced he will work with former Wimbledon champion Richard Krajicek for the grass-court season.

The Swiss player, who reached the semi-finals of the recent French Open, will join forces with Krajicek for the first time at London's Queen's Club tournament.

Wawrinka has never been beyond the quarter-finals at Wimbledon and said it will be a "privilege" to add the 1996 champion to his coaching team, which includes Magnus Norman and Yannick Fattebert.

"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," Wawrinka posted on his Facebook page.

"Magnus, Yannick and I are really excited about the new addition to our team - 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."
