Hans Segers has joined the coaching team at Fulham.
Jol has linked up with Hans Segers again after appointing him the club's goalkeeping coach.
The recently-appointed Dutchman has brought in fellow countryman Segers to fill the role vacated by Kevin Hitchcock.
Segers worked with Jol at Tottenham, while Ray Lewington has been promoted from a youth coaching role to one of Jol's assistant.
"[Hans] comes from PSV Eindhoven, I worked with him in my time at Spurs so I know him very well," he said.
"We started off with Ray Lewington because he's probably a main figure here, at this club, he knows everything.
"He was here when Roy [Hodgson] was here and working here for the academy when Mark [Hughes] was here, so I think he's a key figure here."
Jol had already previously drafted in brother Cornelis Jol and Michael Lindeman to the management set-up at Craven Cottage.
