Lyon may be forced to pass on a permanent deal for Tanguy Ndombele.
The midfielder spent last season on-loan from Amiens and his form has attracted the interest of Manchester City and Inter Milan.
An unnamed agent, speaking to Le Phoceen, believes with OL keeping hold of Nabil Fekir it could mean they will have to sacrifice Ndombele.
"If Lyon does not sell Fékir, they may have to leave Ndombele in Paris (PSG) or Inter," said the agent.
"They will seek to recruit another defensive midfielder."
