Son Heung-min returned to spearhead Tottenham's devastating second-half performance as they came from behind to thrash neighbours West Ham.
Mohammed Kudus had put the Hammers in front with a fine first-half effort but, after Dejan Kulusevski levelled, Julen Lopetegui's visitors fell apart after the break in diabolical fashion.
Yves Bissouma put Ange Postecoglou's side in front before a comical own goal, eventually given to Alphonse Areola after some pinball following a Son shot, made it 3-1. The South Korean superstar soon added a fourth before Kudus lost the plot by pushing two Spurs players in the face late on and was eventually sent off after VAR intervened.
Here are the talking points from Tottenham Hotspur Stadium.
Substitute shambles
Tottenham had not long made it 2-1 when three West Ham substitutes lined up near the halfway line ready to come on. By the time they entered the field of play it was 4-1.
Six minutes had passed with Edson Alvarez, Crysencio Summerville and Carlos Soler watching idly as the XI on the pitch fell apart with dismal consequences.
And it was difficult to understand what the hold-up was. Did Julen Lopetegui want to wait for the game to settle down? Was there a technical issue?
Either way it was a shambolic moment that summed up a shameful spell of football from the away team.
Sharp Son
After three weeks out with injury the Spurs skipper showed no signs of rustiness with a ruthlessly efficient performance.
Having come desperately close with a spectacular effort in the first half, he dragged Tottenham to a higher level during their decisive burst early in the second half.
His own goal did not arrive until the fourth but it was his shot that led to the third goal, awarded to Areola after three deflections, while he also hit the post and created two clear opportunities before being taken off with the points secure after 70 minutes - to a predictable standing ovation.
Brilliant Bowen
Jarrod Bowen looked heavy-legged in the opening weeks of the season, no doubt carrying lingering fatigue from England’s Euros heartbreak. But being dropped by interim national team head coach Lee Carsley appears to have invigorated the Hammers captain.
He looked outstanding against Ipswich before the break, possibly enjoyed the rest over the past fortnight and from the start of this game he caused Destiny Udogie all sorts of problems.
His cross for Kudus’ opener came from a third successful beating of the Tottenham full back.
It was hard to pin too much blame on him for West Ham’s horrific second-half collapse. Bowen, undoubtedly, has to be held as one of the best players outside of the big seven clubs.
Kudus nightmare
What was Kudus thinking? The kick up Micky van de Ven's backside as the Spurs defender lay on the floor was daft, the shove in his face even worse.
And for good measure the Ghana star then pushed Pape Sarr in the head.
The only issue was it took so long for referee Andy Madley to show the red card when it was the most obvious dismissal of the season.
Mixed Areola
Alphonse Areola appears to be alternating between wondrous saves and soft concessions.
This was the second game in a row when West Ham’s No1 was beaten too softly - allowing Dejan Kulusevski’s shot to scramble in at his near post for the equaliser before Son’s fourth also crept by.
Lopetegui’s team are coughing up far too many opportunities in every game and the Frenchman has made a host of spectacular stops already in this campaign.
But he then ruins that all by being beaten from far more routine efforts. His kicking, meanwhile, is a whole other issue - evidenced by a lame pass that led to Spurs’ third.
