United had several chances but was unable to convert.
“It is frustrating. I think we dominated the game, but we just needed a little bit of luck,” Ferguson said.
“Their goalkeeper made two fantastic saves at the end.
“But you have to be worried about the counter-attack that you could lose it also. (Luka) Modric had a terrific shot near the end that just glanced over that could have embarrassed us.”
He added: “Tottenham are not an easy team to play, they are on a high at the moment. Since Harry has come in they have been rejuvenated.
“It’s not the worst result but I would have liked to have got an extra two points as that makes a huge difference.
“After the draws today you hope to take advantage, but now hopefully there will be a draw tomorrow at Chelsea.”
