The Chelsea winger said: "I know the rivalry well. I grew up with it and a lot of fans have come up to me this week and said we HAVE to beat them.
"It's a big game at any level but a cup final increases it even further. Whoever wins this one will have bragging rights for a long time to come.
"Ever since I can remember it's been a tense rivalry and I expect it will be a heated game. We'll have to call on all our experience and, hopefully, get the job done."
He added: "I like the way Spurs play. And I like their players, particularly the English boys as well as Berbatov and Keane. We have to respect them because, for me, they're a top-four side.
"And we have to play better than we did against Olympiakos. They tried to close the game out but I think it could be a lot more open against Spurs."
