Coach Kristijan 'Kiki' Schneider Passes Away At 41

Croatian had also worked on the WTA Tour

The tennis world is mourning the loss of Kristijan Schneider, former coach of Croatian Borna Coric, who has passed away aged 41.

"Rest in peace my friend and my coach. I was blessed to have you in my life," wrote former World No. 12 Coric in tribute to his countryman on Twitter.

Schneider, also known as “Kiki”, had been battling abdominal cancer. Those involved in a fundraising effort to support his treatment included Italian World No. 197 Thomas Fabbiano and Gilles Cervara, coach of World No. 2 Daniil Medvedev.

Another Croatian, WTA star Ana Konjuh, paid tribute to Schneider on Instagram. “I’m lost for words. Until we meet again, save me a hug up there. Rest in peace Kiki,” wrote the 24-year-old. Schneider also had a stint working on the WTA Tour as coach of Serbian Olga Danilovic.

ATP World No. 29 Frances Tiafoe added his own tribute in response to Konjuh’s post. “Had nothing but love and respect for you Kiki," wrote the American. "Thankful for our friendship."
