Japanese tennis star Kei Nishikori has decided to split from his long-time coach Dante Bottini as he believes it's time for a change. Nishikori, 29, has achieved some notable success under the guidance of Bottini but he hasn't fulfilled his biggest goals.
Nishikori, a 12-time ATP champion and former world No. 4, hasn't had a great season. World No. 9 Nishikori captured the Brisbane International title in the first week of the season but since then hasn't taken part in any finals.
Nishikori has managed to reach a final at the Grand Slam and Masters 1000 level while coached by Bottini level but he hasn't yet achieved his goal of winning a title on the biggest tennis stage. "After nine years of working together literally day in and day out, I have decided it is time for a new voice.
I am forever grateful for Dante’s contributions to my career and we will obviously remain very close friends. I appreciate so much the last nine years and our friendship," Nishikori announced via his Twitter account.
Nishikori will continue working with 1989 French Open champion Michael Chang while he seeks a replacement for Bottini. Nishikori hasn't played since the US Open due to an injury.
