Dominic Thiem has dumped 1995 French Open champion and former world number one Thomas Muster as an adviser just weeks after hiring him, but insisted Monday "nothing bad happened".
The world number five, who is chasing a maiden Grand Slam breakthrough at the Australian Open, brought Muster on board this month after he served as captain of the Austrian team at the inaugural ATP Cup.
He was due to make himself available for 20 weeks this year, working alongside Thiem's coach Nicolas Massu.
"Well, nothing bad happened there. But we already said before we started the relationship that if it doesn't work out, we're gonna stop it, and that was the case," Thiem said after moving into the Australian Open quarter-finals.
"I mean, I think it's always difficult, especially for me at the stage where I am, to find something perfect to add to my team.
"And I just had the feeling that it's not going to work out together, and that's why we finished. So that's all."
