The Dutch goalkeeper produced 14 saves at White Hart Lane to constantly deny the Spurs attack and admits it is the best he has ever played at the top level.
"No. This is the highlight of my career," Krul told Sky Sports when asked if he has ever played better.
"That doesn't happen very often, this type of game. Three points away at Tottenham is a fantastic result.
"I'm delighted. I'm over the moon. Hard graft, I think the boys worked their socks off again like last week (against Chelsea) and we dug it out.
"We know the Premier League is unforgiving. Today we got three points, but it was a hard game. We have got two home games to come, though, so we can look ahead with confidence."
