The American midfielder does not like how he was portrayed in the days leading up to his move from Craven Cottage to White Hart Lane but says that is all in the past now
The American looked to be one of Liverpool's top transfer targets in the window, and turned down the opportunity to join Aston Villa after a bid was accepted by Fulham.
But the Anfield side seemed unwilling to match the €7.6 million fee for Fulham's top goalscorer of last season, and a late switch to Spurs transpired on deadline day.
However, Dempsey is unhappy with people who have questioned his attitude following his departure from Craven Cottage.
"Everyone has the right to their own opinion, but I put in some good work there, put in a good five-and-a-half years, and I'm happy with the job that I did there," the American midfielder told reporters.
"I think that you can't really question my heart. I put everything into every game and that's what I've always done my whole career. I'll look back at my time [at Fulham] with no regrets."
After months of being linked to a move elsewhere in the Premier League and constant rumours regarding his relationship with Jol, Dempsey finally ended up with Tottenham just hours before the transfer window closed. He had been training alone with a Fulham coach prior to making his exit.
He added: "I'm disappointed with the way things ended and how I was portrayed in the end, but that's in the past now.
"I just want to thank the fans for five-and-a-half great years and thank the chairman for taking a chance on me from MLS. I'll always look back at my time there with a smile on my face."
Dempsey was left out of Fulham's line-up for the club's first two games of the season and has not played in a competitive game since last June, a streak that will likely end when the US national team takes on Jamaica in the first of two World Cup qualifying games between the teams in a five-day span.
"It's good to have that behind me now and now looking toward the future," he continued. "I'm excited about the qualifiers coming up with the US team but also excited about the opportunity of playing for a team like Tottenham and working hard and trying to break into that lineup.
"It's definitely been a roller coaster, you know, up and down. It definitely was a stressful time because you don't know where you're going."
