Having seen through the danger to move seven points clear of their North London rivals, however, the England international - now with 23 league goals to his name this term - hopes to maintain the feel-good factor around temporary home Wembley.
"It was a great game, we really played well, especially second half we had plenty of chances after we went 1-0 up," he told Spurs TV. "It's crazy it finished 1-0 but we'll take it. In these big games you just need that first goal and the spaces open up and you get more chances.
"That's what happened, we should have been more clinical, we know that, but we played very well. We kept them quiet until the last five minutes when they piled on the pressure. But overall it was a good day.
"It's massive, it's a big stage in our season and we've come out in flying colours. We've got good momentum, the Champions League coming up, which we're looking forward to, then we've got to keep it going in the league."
After facing Juventus in Turin on Tuesday night, Spurs then head to Rochdale in the last 16 of the FA Cup five days later.
