The former Spurs boss appeared at Motspur Park this afternoon to introduce himself individually to the management team and staff.
"I’m very happy to be back and especially at a club like Fulham," Jol told the official Fulham website. "I remember coming here with Tottenham and I even think I played here when I was a player. Craven Cottage is a real football stadium, I loved going to Fulham."
Jol said he would now evaluate the current squad ahead of their first Europa League fixture at the end of the month.
"It is too early to say that I know a lot about the squad I have inherited, but I enjoy watching Fulham and I enjoy watching players like Dembele who I have known for a while," he added.
"There are a few players here I still know from my time at Tottenham, like Simon Davies, Danny Murphy and Stephen Kelly – they are all very good professionals.
"Yesterday we had a good conversation about players and where we can try to strengthen and get one or two quality players."
