Spurs may have found some form under new boss Tim Sherwood to record a hard-earned 2-1 win at Manchester United on Wednesday, but Walcott maintains tackling the league leaders on their own ground will be a whole different ball game.
"I think it is going to be a bad time to play us as well. For the neutrals it is going to be a very interesting battle," said Walcott, whose well-executed chip in stoppage-time helped seal victory against Cardiff after Nicklas Bendtner's 88th-minute goal had finally broken the visitors' determined resistance.
"The FA Cup is always special, for me, being English as well. I love the FA Cup. I can't call it. It is one of those games that is going to be very open. Tottenham, since their new (managerial) appointment, have done very well to be fair to them but, like I say, they won't want to play us.
"It is at the Emirates - we are trying to make our stadium into a fortress and we are starting to do that."
