Mason Mount missed the critical spot-kick as Tottenham Hotspur came from a goal down to beat their London rivals Chelsea on penalties to seal their place in the quarter-final of the EFL Cup.

Both managers call up changes from the weekend’s Premier League games but Timo Werner kept his place in the Blues line-up and strike his first goal in English football after a mistake from Tottenham debutant Sergio Reguilon.

With a Europa League play-off to contest on Thursday, Tottenham’s only survivors from the 1-1 draw with Newcastle on Sunday were Hugo Lloris and Eric Dier, with Dele Alli miss out from the squad once more.

Edouard Mendy replaced Kepa Arrizabalaga for his Chelsea debut but had nothing to do in the first half the visitors dominated with the quirk of a comfortable save with his feet to deny Erik Lamela’s straight forward shot.

Tottenham were much improved after the restart, with Reguilon forcing a good save from Chelsea’s new shot-stopper, who then had a concerned moment after twitch at a corner delivery.

But he could do nothing with Lamela’s late equalizer, who nudge home after Reguilon made atonement with a fine cross to provide the assist.

With extra-time throwaway, the tie went to penalties. The first nine spot-kicks were perfect before Chelsea’s fifth taker, Mount saw his hit the post and go wide.
