Nantes chairman Rudi Roussillon has backed goalkeeper Fabien Barthez.
The former Manchester United ace cost his side defeat at the weekend after he spilled a cross into his own net.
Moments after the mistake he was substituted and he left the stadium almost immediately.
At the time it was presumed Barthez was injured - but coach Michel Der Zakarian has revealed this was not the case.
"It is shame to have conceded such a stupid goal," Der Zakarian told RMC.
"Fabien made a gaffe that cost us a lot. He wasn't injured when he left.
"I won't reveal what he told me, it is something internal.
"He is alright now, back to training.
"To me, Fabien remains an example of professionalism."
Roussillon also threw his support behind the legendary shot-stopper.
"I have spoken to him several times on the phone since Sunday," he said.
"He explained to me why he left. He wanted to go and tend to himself in peace, at his house. That's fine, I can understand that.
"I felt he was touched by this defeat, that's a sign that he is part of this group and not on the outside.
"There is no problem - he assured me he would do everything to help Nantes escape, as he did when he first arrived (in January).
"A Barthez in the best condition can allow us to stay in Ligue 1. For me, he remains a model professional."
