Petric has been forced to play second fiddle to star man Dimitar Berbatov, making a further 13 appearances off the bench.
“Petric is one who could make his mind up himself because as long as Berbatov was here, there is not a big role for him to play,” Jol told the Fulham Chronicle.
“The only thing is if you see his minutes he is very productive.
“He has said that he needs to play, which is what they all say. And if he needs to play, I’m not sure he will stay here."
