**West Ham United 0 Tottenham Hotspur 3**
Thomas Frank heralded his Tottenham Hotspur side after what became a procession over a flat, ten man West Ham United at the London Stadium.
The manner of Tottenham's victory was comfortable, as they dominated a second half where the Hammers offered no response. Scant chances and little aggression characterised the hosts' performance which will pile more pressure on manager Graham Potter who has now presided over three defeats and a single victory in the first four games of their Premier League season.
Spurs, on the other hand, sit second in the table, just behind north London rivals Arsenal on goal difference.
Following a fairly evenly matched, if drab, first half, Frank's team took control shortly after the interval. The Hammers suffered the loss of Tomas Soucek, who was sent off in the 54th minute - a straight red for a late lunge on Joao Palhinha.
Pape Matar Sarr headed high into the net seven minutes earlier - undoubtedly a poor goal to lose from West Ham's defensive perspective. That set the tone, and any concrete response was not to be forthcoming in a largely one-sided capital derby.
It was a measure of West Ham's frustration that Soucek departed the scene and a couple of minutes later, Lucas Bergvall delivered the second for Spurs with a well placed, looping header from Cristian Romero's deep, angled cross.
Spurs were strolling in east London and in the 63rd minute, West Ham's misery was complete when, seizing upon a misplaced shot by the very impressive Bergvall, Micky van de Ven swept home a low drive from around eight yards out, with the hosts' rear guard once again totally inattentive.
"Not too much happened in the first twenty minutes, but we grew into it and dominated", said Spurs manager Frank, who rotated his team with Tuesday's Champions League tie at home to Villarreal in mind.
"I am happy that the goal came when it did in the second half. A very good, clear win and a very good performance. We all know the importance of this game for the fans. It is difficult to play here so to win 3-0 is very impressive. I'm very happy with the squad overall.
"It's crucial that we defend well too to give us foundations for clean sheets", added Frank, who also praised Bergvall and Palhinha.
From West Ham's perspective, the manner of this is to a huge worry. Their players were completely all at sea, lacking sufficient work rate when going behind - a desperately woeful second half will further add to the flak manager Potter is enduring.
Yet perhaps the most relevant aspect was the sheer apathy from the stands, where only a small number of hardy supporters remained until the end of this bleak fare for West Ham.
Their collapse and failure across the basics of of defending set pieces for instance is all the more perplexing in view of how well Potter's team played in their 3-0 win at Nottingham Forest before the international break. It appears that particular day is an outlier in the wider problems Potter is confronting. How he needs to get the West Ham fans back and in fervour.
Nevertheless, with practically the entire second period spent with Tottenham ambling at will inside the Hammers half of the pitch, that in itself is beyond unacceptable. Consequently, the former Brighton boss is under serious heat.
As comfortable as Tottenham were at the London Stadium, West Ham frankly made it all too easy for them.
Potter tried to accentuate a better first half from West Ham before the alarming slump.
"The first half was even and we had some good moments", said the Hammers chief.
"From a defensive perspective we were solid (in the first half) but in the second half we made a mistake for the first goal. Then there was the red card and the game really just got away from us".
Potter admitted he felt "frustrated" on behalf of the fans.
He added: "When the score line went away from us so quickly, it was an uncomfortable evening for us all and I felt for the supporters.
"I understand the frustration, We've played two games at home, against Chelsea and Tottenham who are in the Champions League and can build big, good squads. We played well against Forest but I can understand the reaction when you see the score line.
"The form hasn't been good at home for some time, but because of how the second half went it appears negative, and we should try and look at the good things in the first half".
