Ghana superstar Andre Ayew scored twice for West Ham to stage a remarkable second-half comeback to come from two goals down to beat London rivals Tottenham and reach the Carabao Cup quarter-finals.
Hammers boss Slaven Bilic has been under pressure following their Premier League drubbing by Brighton at London Stadium on Friday, but will surely be enthused by the reaction to their abject first-half showing against Spurs.
Striker Andre Ayew netted twice from close range and Angelo Ogbonna nodded in the third from a corner to complete a stunning turnaround.
They had got off to the worst possible start at Wembley, conceding after just five minutes as a high defensive line was exploited by Son Heung-min's pass through to Moussa Sissoko to stroke home.
Dele Alli had a close-range header tipped away by goalkeeper Adrian, but the Tottenham midfielder curled in a deflected second before half-time from the edge of the box following neat build-up play by Son.
Spurs could have taken the tie to extra time, but Alli's thumping volley and Sissoko's curled effort were both kept out by Adrian.
The draw for the next round takes place live on Twitter at 16:00 BST on Thursday.
