Jose Mourinho accused his Manchester United stars of failing to follow instructions after Christian Eriksen scored just 11 seconds into Tottenham's 2-0 win at Wembley.
United boss Mourinho was furious with his side's sloppy defending as they made a host of mistakes that allowed Eriksen to blast Tottenham ahead with the joint second fastest goal in Premier League history.
Phil Jones allowed Harry Kane to win a header from the kick-off and, with the rest of the United defence caught flat-footed, Dele Alli pounced with a deft pass that Eriksen steered home from close-range.
Adding insult to injury for Mourinho, Jones booted a Kieran Trippier cross into his own net midway through the first half to double Tottenham's lead.
"I don't think it is very normal to concede a goal like we did after 15 seconds," he said. "It is especially ridiculous because the players, they watch it before, we analyse opponents and work on opponents' dynamics and routines.
"The players they knew the long ball, they knew that Harry Kane - before the kick-off, is already inside the opponent's half. We knew everything.
"Then we don't press the ball - one mistake. We don't pick the ball in the air - second mistake. We don't win the second ball on the ground - third mistake.
"We don't cover the inside when Eriksen comes - four mistakes. Four mistakes after 15 seconds and you are losing 1-0 against a good team."
With second placed United clinging to faint hopes of catching leaders Manchester City, it was a badly-timed meltdown from Mourinho's men.
They are now 15 points behind City and Mourinho admitted he harbours no hopes of catching Pep Guardiola's side. Instead, he will focus on ensuring United survive the fight to qualify for next season's Champions League via a top four finish.
Tottenham's win puts them just two points behind fourth placed Chelsea and third placed Liverpool, with a crucial trip to Anfield looming on Sunday.
Mauricio Pochettino was enthused by the way his team dominated such formidable opposition, but the boss refused to rate it the best of a season that also includes impressive wins over Real Madrid and Liverpool.
"I don't know if it was the best, but for sure one of the best. The performance was fantastic," he said. "Manchester United are a great team, so to dominate and to keep a clean-sheet, the team deserve a lot of praise of course."
Antonio Conte had no doubt the pressure on his position would intensify after his Chelsea side's stunning 3-0 defeat by Bournemouth at Stamford Bridge on Wednesday.
The Blues head coach insists his Chelsea team, the reigning Premier League champions, are over-achieving this season -- but claims he is "relaxed" if members of the club's hierarchy view things differently.
Defeat left Chelsea in fourth place in the Premier League, just two points above Tottenham Hotspur and Conte accepted there were concerns over whether the Blues would qualify for next season's Champions League.
"The pressure, it's normal. It's normal for a coach, for a manager," Conte said. "It's normal if you are Chelsea's coach.
"After the first game this season, you (the media) tried to put pressure on my job. But I'm trying to do my best."
