Olympique Marseille president Jose Anigo cannot guarantee Marcelo Bielsa staying.
The OM coach, off contract in June, has been linked with West Ham United and Newcastle United in England.
"It is not a question of the man, I appreciate Bielsa, he is a great coach, but nobody is irreplaceable at this club.
"The only thing that matters is the club itself," said Anigo.
"I think everyone at the club wants Bielsa to stay."
