Visiting Spurs are considered to be the favourites to advance past the Canaries at Carrow Road.
With that in mind, Wales international Bale has called upon his team to collect a "good result".
"They're a team that works hard for 90 minutes and they're going to give us a hard time, so we'll have to be fully prepared," he told reporters.
"We'll have to sit down and have a look what their weaknesses are. Hopefully we can exploit them and come away with a good result."
Reports have claimed that Bale will be named on the Tottenham bench for the match.
