Cesc Fabregas scored twice in extra time as Chelsea came from two goals down to beat 10-man Leicester and reach the EFL Cup fourth round.
Shinji Okazaki’s header and instinctive strike put Leicester in control, but Gary Cahill nodded in before the break.
Cesar Azpilicueta equalised with a long-range effort before Foxes defender Marcin Wasilewski was sent off.
Fabregas’ clipped finish put Chelsea ahead early in the first extra period and a powerful shot sealed the win.
It had been a pulsating cup tie – particularly in the second half – with chances at both ends but Wasilewski’s dismissal for elbowing Diego Costa ultimately proved costly.
Chelsea deserved to progress but Foxes boss Claudio Ranieri will perhaps be buoyed by his side’s performance for much of the game, with glimpses of the incisive attacking and compact defending that helped them win the title last season.
Man of the match – Cesc Fabregas
