Dempsey, who moved to Tottenham on transfer deadline day, cites the run as one of the highlights of his career, and he now hopes he can go one better with his new employers.
"It was tough for us to get all that way and not win the final, but it was a great experience and I'm sure everyone on that team will remember it," Dempsey said ahead of Spurs' clash with Panathinaikos.
"We had luck then and we need that now, but we do have a lot of quality in this team.
"As long as everyone is working hard and focused, you always have a chance.
"And with the quality we have, I can't see why we can't go all the way and win it."
