Jol was sacked from his post as Spurs boss after winning one of the club’s first 10 league matches of the 2007-08 season and subsequently had his contract terminated.
Jol is believed to have received a text from Spurs chairman Daniel Levy telling him of his sacking during a Uefa Cup group stage match against Spanish side Getafe, but said there is no bad blood between the two, thanks in part to the Dutchman's successful move to German side Hamburg.
Speaking to reporters at his unveiling as Fulham boss, Jol said: “I won't lie, I didn't feel great at that moment [the end of his reign at Spurs].
“But later on you go to another club. I was in Germany, and Hamburg have 55,000 season-ticket holders, not bloody 30,000, so that was a bigger club.
“I played in the semi-finals in Europe, and I played in the quarter-finals with Spurs, so it was even better. There's no looking back, no hard feelings.
“A couple of years ago Daniel [Levy, the Tottenham chairman] phoned me up as if nothing had happened, so that helped. He looked after me — and why not? I did well for him."
Jol will come up against his former club when the two sides meet at Craven Cottage on November 5 in a Premier League clash.
