Tottenham Hotspur held off a spirited comeback from West Ham United to advance to the Carabao Cup semi-final after a 2-1 victory.
A frantic six-minute spell in the first half saw the game explode into life as the London rivals traded goals like Christmas cards.
Fantastic play from both Pierre-Emile Hojbjerg and Stephen Bergwijn unlocked the stingy Hammers defence, before Hugo Lloris was forced to make a brace of brilliant saves.
It mattered little when Jarrod Bowen punished Eric Dier’s costly mistake, only for Lucas Moura to restore Spurs’ lead.
There was to be no dramatic comeback for the visitors unlike last season in the Premier League, when they found three goals in eight minutes to salvage a 3-3 draw.
Instead, Antonio Conte’s well-drilled side held on to secure passage to the final four, where one of Arsenal, Leicester or Chelsea await.
Spurs took the lead after great work down the inside right channel, with Bergwijn collecting a swift past from Skipp inside the box after Issa Diop missed his interception.
The Netherlands international then fed the onrushing Hojbjerg, who calmly squared for Bergwijn to tap home – despite the best efforts of Ben Johnson on the line.
It seemed to spark an instant reaction from the Hammers, with Nikola Vlasic sending in a swirling cross for Tomas Soucek, but the Czech Republic international was denied by a stunning save from Hugo Lloris.
The World Cup-winning goalkeeper was at it moments again, tapping over the resulting corner, before he was left in no man’s land from the resulting set-piece and Craig Dawson nodded wide.
Tottenham clearly did not heed their warning and were punished when Eric Dier’s lax pass from a goal kick was pounced on by the Hammers and fed to Jarrod Bowen, who turned the guilty centre-half inside out before firing past with his right foot.
Trevor Sinclair on talkSPORT 2 said: “Conte has said Dier can be one of the best centre-backs in the world, he won’t be if he plays like that.
“I don’t even know he is looking at there, he has tried to thread a ball into midfield that is just not on.”
Yet the sensational six minutes would end with the hosts restoring their lead after a great burst from Bergwijn on the right hand side yet again past Manuel Lanzini and he fed Lucas Moura – who had the simple task of tapping in from five yards.
The east End outfit almost instantly equalised yet again, only for a wonderful challenge from Skipp at the back post to deny the dangerous Soucek as he slid in desperately.
West Ham made a brilliant start to the second half, dominating possession and looking dangerous through Bowen again up top yet he was crowded out on two occasions after excellent runs.
It prompted immediate action from Antonio Conte, with Heung-min Son thrust on instantly alongside Harry Winks in a bid to regain control of a chaotic London derby.
It proved to be a masterstroke as the Hammers could not make their 70% possession count and failed to force Lloris into yet another save, crashing out of a competition they had serious designs on winning after knocking out Manchester United and Manchester City.
