Crystal Palace have enjoyed some luck in their FA Cup run to date.
Along the way to the quarter-final, Palace have beaten Southampton away and Stoke City at home and in the wake of the Spurs victory, Pardew is hoping his side's fortune continues as they now prepare to take on Reading in March.
"We had a bit of luck today, when Alli hit both posts, so hopefully that continues.
"We learned some lessons from the two Tottenham games before."
And Pardew also praised Martin Kelly who scored the only goal of the contest when racing forward to receive a through ball from Wilfried Zaha before firing beyond Michel Vorm for his first goal for the club.
"We changed the shape so we didn't get pushed back so far but in doing that, we had to release our full-backs to get forward," he added.
"To get that goal from a full-back shows the kind of intent that we had."
