The Cottagers player was converted from a forward to a midfielder by Martin Jol last season and the Belgian has attracted interest from Champions League clubs as a result
Martin Jol converted the Belgian from a forward into a central midfielder during his first tenure at Craven Cottage and it has had a positive effect on his form and market value as a result.
He told the Fulham Chronicle: "I'm very happy to stay at Fulham, especially because of the boss.
"I think it's very important to have the backing of the manager and he's a coach who gives me a lot of confidence - that's why I feel I owe it to the gaffer as well.

"I think every player needs that and I'm no different. I go to training every day and work with joy. It's a fantastic club and I'm not in a hurry to move anywhere."
Jol's decision to move him into the centre of midfield has pleased the Belgium international and he hopes their form in the second half of the Premier League season can be carried into the next campaign.
He added: "I'm very happy with the change this year in the position I play because I'm a player who likes to have the ball as much as possible - and that is down to the manager as well.
"I think I can hold the ball very well - and it's an advantage to the team if I have a lot of the ball, so I like that position a lot.
"I'm also very happy with the way the season went. The club is doing very well and we have a very strong team with good players.
"Next year, everybody wants to do even better. I'm not sure what will be our target next season, because in a way it's the club and manager who decide.
"I don't know if it is realistic to try for fourth or fifth or sixth, but I think we should look to do even better than this season and last.
"Maybe we will have more energy because we don't play in Europe this season and we can concentrate on the league."
