David Moyes slammed referee Howard Webb's decision not to award Manchester United a penalty after a challenge on Ashley Young by Hugo Lloris.
United lost the game 2-1 and they were chasing an equaliser when Spurs keeper Hugo Lloris came racing out to meet Young, who was charging into the area.
The winger suffered a bang on the left shoulder as he fell to the ground, but Webb remained unimpressed, rejecting the penalty claims - much to the disgust of Moyes
"It was scandalous, a scandal" said the United boss. "If you follow through on a player anywhere else on the pitch with your foot high, it would be a sending-off and a red card. You couldn't do that anywhere else.
"The goalkeeper comes out, Ashley Young gets the ball before him and he follows through.
"It's an incredible decision which didn't go our way, in fact probably the one of the worst I think I saw."
Moyes' mood was not improved by Adnan Januzaj's booking, for diving, for the third time this season.
"Have you seen that decision? That is a terrible decision," said Moyes. "Adnan has got bumped. The boy has tried to edge him off the ball.
"All I can tell you is that (Lloris' challenge on Young) is a stonewall penalty kick. If that isn't given a penalty kick, I don't think we will get any more in the league this season.
"It is reckless, it is late, it is in the penalty box. I don't know what else you can say.
"You'd hope the people who put the referees out there would have a look at it and see if they think the referees are doing as well as they can be."
The defeat was United's fourth at home in the Premier League this season, which left them 11 points behind League leaders Arsenal.
"I am not frustrated," said Moyes. "I thought we played really well. Today was a defeat of course, but we deserved to win, or at worst draw."
The return of Wayne Rooney to the starting line-up was a positive Moyes, but he admits the striker may have to be used sparingly in the coming weeks because of his groin issues.
"If I could (rest him), I would," said Moyes. "But the games are coming thick and fast.
"He has missed a couple with his groin and may well miss some more in the games coming up."
Moyes said it was too soon to know if Robin van Persie, who has missed the last six games with a thigh injury, will be fit to return for Sunday's FA Cup tie against Swansea
"I'm not sure yet," noted Moyes.
Moyes insists though that the loss setback has not affected his plans for the January transfer window.
"The result today would never have any effect on what we do, whether in January or the summer," he said.
"It wasn't our day but it won't change the way we go about our business."
