Tottenham captain Ledley King admits it was difficult to lift his teammates after their derby defeat at Arsenal.
Spurs host Sunderland this weekend.
"Everyone was down afterwards because we knew we were in the game and we blew it in the space of the minute," King told the Spurs website. "That minute dictated the course of the game. We're better than that and that's the disappointment.
"We don't want to lose to Arsenal, full-stop - and we never want to lose 3-0 to anyone. We know how much this game means. We're all disappointed.
"We have to pick ourselves up now. It's one game and I'm sure this will hurt for a few days yet but once that's over we have to focus on the next match and try to get back to winning ways against Sunderland."
Ledley said the two-goal spell was 'crazy'.
"We were still trying to get our heads around the first goal when we restarted and 10 seconds later the ball was in the back of the net again," he said. "From our point of view, that just can't happen.
"All of a sudden we've come off for half-time and it's a totally different game.
"I think we showed the right spirit in the second half, again, apart from the goal. We kept trying to do the right things but it was a very disappointing day at the office, to say the least."
