Tottenham’s fans high in the Leazes Stand had no stomach for any more humiliation with many heading for the exits and the long journey back home long before half-time.
The only question left was whether Newcastle would claim their biggest Premier League victory and whether Tottenham could avoid their heaviest top-flight defeat.
Tottenham improved after the break, although it was hard not to, with Harry Kane slotting in a consolation goal four minutes into the second half but Callum Wilson scored Newcastle’s sixth one minute after coming off the bench.
It was the perfect response by Newcastle to last week’s 3-0 defeat at Aston Villa and took them a big step closer to a return to the Champions League for the first time for 20 years.
Newcastle moved above Manchester United into third place with 59 points, six more than fifth-placed Tottenham who have also played a game more and whose hopes of a top-four finish now look to be all but over.
