Kristina Mladenovic expressed, Sunday, his disappointment after the decision of the German Sascha Bajin not to train him while the duo worked together for six months.

"I am very disappointed with Sascha's decision not to continue our collaboration for next season, but I can not change her opinion or her decision," writes La Française on her Twitter account.

"I liked our work, we had great victories and I feel that my game is back on the right track, I think we could have accomplished even more things together," added Mladenovic 26 years.

On 12 February, Sascha Bajin, a former training partner of Serena Williams, was thanked by Japan's Naomi Osaka, then World No. 1, for her second straight Grand Slam victory, the Australian Open.

Sascha Bajin received, thanks to his Japanese protégé, the WTA trophy for best coach of the year 2018.

Kristina Mladenovic, a semi-finalist in Moscow on Saturday, won 26 games against 17 defeats under Bajin's leadership, which took her from 66th in the world (mid-April) to 39th Monday.
