Nine spot-kicks were converted with the minimum of fuss, so Mason Mount had to score, but the midfielder’s effort clipped the outside of the post and went wide. It brought to an end our four-game winning streak against our north London rivals, and was made all the more frustrating considering the timing of Tottenham’s equaliser.
During regulation time, Werner had given us the lead with his maiden Blues goal, a confident finish from 18 yards out midway through a first half we largely dominated. Cesar Azpilicueta did brilliantly to set him up.
Tottenham were much improved after the interval and Edouard Mendy, on debut, did very well to deny Sergio Reguilon an equaliser. Our new Senegalese stopper had also kept out Erik Lamela in the first half.
As the contest opened up, we had chances to put the tie beyond doubt, but they were not taken and when another opportunity came Tottenham’s way with six minutes left, Lamela made no mistake.
So to penalties it went and after a flawless set of five from the home side, and four confident Chelsea efforts, Mount’s miss proved the deciding factor, ending our interest in this competition at the fourth round stage for the second straight season.
In total there were eight changes to the side that started at West Brom, one of which was Mendy. Ben Chilwell made his full Chelsea debut at left-back, and there were also starts for Fikayo Tomori, Callum Hudson-Odoi and, for the first time this term, Olivier Giroud.
