Tottenham produced a 7 minute blitz in the second half scoring 3 goals in quick succession.
Another bad day at the office for Van Gaal.
“The first part of the first half we were the better team,” he said.
However it was the three goals from Dele Alli, Toby Alderwereld and Erik Lamela in the second half that blew them away.
It was the first time Tottenham have beaten United at home in the last 15 years – and what a way to win.
United are also facing the prospect of a fine of at least £5,000 after kick-off had to be delayed by 30 minutes due to their late arrival. It is understood that the Manchester United team bus only left the Landmark Hotel in central London at around 1.45pm for the scheduled 4pm start and then had to be diverted after they could not get under a bridge.
Tottenham keep close behind Leicester City as the season heads towards the final straight.
