Helena Costa has remained tight-lipped over why she decided to step down as coach of Clermont Foot, but stressed that it was her decision.
Costa became the first female coach of a professional men's club in the top two tiers of any European league when she was appointed last month.
No reason was given for her decision to step down from the French second division club on Monday and any hopes that a press conference would clear things up were soon dashed.
Costa, 36, said that she had gone through her reasons with club president Claude Michy and that she would not disclose them publicly.
"I had a lot of points that I discussed personally with the president and after that discussion I took my decision," Costa told reporters.
"The president knows exactly what it is and he's the only person that I have to discuss (it with)."
She said that it was not something she had taken lightly and she hopes she will be given more opportunities in the future.
"I thought over my holidays so of course I would appreciate if I could continue but it was my decision so I have no reasons to be sad," she added.
"I hope in the future other opportunities will come."
