Jol has spoken with the former Gunners man about extending his stay at Craven Cottage with his contract running out in 2014.
He said: "We want him to stay. I always like it when players, even if they are not playing, stay positive.
"After Mousa Dembele left, I needed him.
"He was probably the only player I had from the season before.
"He's a character and wants to train extra for the next game."
