Marin Cilic splits with coach Goran Ivanisevic

Cilic won his first Grand Slam at the US Open in 2014

World number 12 Marin Cilic has split with his coach, former Wimbledon champion Goran Ivanisevic.

Croatian Cilic, 27, has worked with compatriot Ivanisevic since September 2013 and won the 2014 US Open by beating Kei Nishikori in the final.

He reached the semi-finals the following year and has three Wimbledon quarter-final appearances to his name.

"I enjoyed our work all this time and Goran helped me to reach many goals," Cilic said on Facebook.
