Magnus Norman has ended his partnership with Stan Wawrinka and in doing so ended one of tennisโ€™ most successful coaching partnerships in recent years.

Wawrinka first hired Norman in April 2013 when he was ranked 17th and his best performances at grand slam level were reaching quarterfinals twice. Norman immediately helped to improve Wawrinkaโ€™s fortunes, helping him reach his first semi-final at the US Open that year and then in January 2014 taking him to his first slam title in Australia.

Since then Wawrinka has won two more grand slams, the French Open and US Open, and he reached the final in Paris this year. He has failed to reach the last eight in just four of the last sixteen slams he has taken part in and his ranking grew as high as number three.

Norman has said that he took the decision in order to allow him to spend more time with his young family.

In a statement Norman said, โ€œAfter much thought I have decided to dedicate my future to my family. With two young kids at home, now is the right time for me to be with them. I could not have had a better player to work with and this has been one of the most difficult decisions I have ever had to make. I’m really honoured to have worked with Stan, who is a great tennis player, but more importantly a fantastic person.โ€

After Normanโ€™s announcement Wawrinka said, โ€œI would like to thank Magnus for the amazing four years we had together. I will always be grateful for the work and the time he spent on me to make me improve and become a three times grand slam champion. He was not only part of my team but also part of the family. For now I’m focusing on my rehabilitation and I will take time to decide with my team the necessary next steps.โ€
