One of the big positives for Jol so far this term has been Parker, the midfielder recruited from Tottenham who made his debut against Arsenal.
The Fulham boss said: "He was exactly the kind of guy we expected him to be.
"He was the only one we spent money on. I think he was worth it.
"I enjoy watching him, the fans enjoy watching him and hopefully he will continue to do that.
"He is a spirit. He wants to win here, he shows us the way in midfield, he works hard.
"He's played all the games (since signing). I needed him (against Everton).
"I really thought it was necessary that Scott Parker played. That shows you how important he is."
