Lyon president Jean-Michel Aulas has revealed that either Milan Baros or Fred will leave the club in the January transfer window.
Portsmouth are keen on bringing Baros back to the Premier League, while a number of clubs are reportedly chasing Fred.
Former Liverpool and Aston Villa striker Baros is believed to be considering his options after Pompey declared their interest in him.
Fred, meanwhile, claims he would be happy to stay at Lyon but Aulas is prepared to let the 24-year-old leave the Stade Gerland.
"It is established between Fred and Baros that one of them will leave the club before the end of the January transfer window," Aulas said
"But I cannot say which one as we are still receiving offers for both of them."
