Helena Costa will not take up her role as coach of Clermont Foot, the French division two club have announced.
The 36-year-old former Celtic scout and manager of the Iran women’s team was appointed to the position in May but has decided not to continue.
Clermont president Claude Michy said: "I deeply regret this situation.I thank all those who have given me their support and I am very appreciative.”
The Portuguese manager, who was set to become the only female coach of a top-two-tier club in Europe, later said she didn't take up the role for personal reasons.
"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."
