"Thank you! After 8 great years together [Magnus Norman] and I have decided to part ways by mutual consent," Wawrinka posted on Instagram. "We have had a amazingly strong, enjoyable and hugely successful partnership. We reached the height of this sport together and I want to thank him for helping me win everything that I could ever dreamt of winning.
"He’s been a great coach, friend and mentor and will always be a dear friend. I want to publicly thank him for all his hard work dedication and commitment in making me a better player over the years. Winning 3 grand slams has been a life changing experience for me and I could not have done that without him. Wishing him all the best in his next chapter in his life!"
When Wawrinka hired Norman in April of 2013 he was ranked No. 17 and had never been beyond a Grand Slam quarterfinal.
Under Norman's guidance, Wawrinka captured 13 titles, including three Grand Slam championships—defeating the reigning world No. 1 in all three major finals—and ascended to a career-high rank of No. 3.
An oustanding player in his own right, Norman is a former world No. 2 and 2000 French Open finalist.
Norman encouraged Wawrinka to play with a bit more spin on his forehand, assert his powerful first serve to set up the first strike and play the score with more care.
Wawrinka, who admitted dissolving in tears in a panic attack before facing then world No. 1 Novak Djokovic in the US Open final, credited his coach with helping him maintain his calm and establishing a clear game plan before his major final victories.
The 17th-ranked Swiss, who upset Novak Djokovic at the 2019 US Open for his fifth win in his last six meetings with world No. 1 players in Grand Slams, advanced to the Australian Open quarterfinals and Doha semifinals this year.
