Carney Chukwuemeka rescued Chelsea with a stoppage-time strike that inspired a 4-2 win over 10-man Leicester in an FA Cup quarter-final thriller on Sunday.
Mauricio Pochettino's side were fortunate to survive a stirring fightback from Championship promotion chasers Leicester amid a mutinous atmosphere at Stamford Bridge.
Chukwuemeka netted in the closing minutes to save Chelsea from the embarrassment of being forced into extra-time. Noni Madueke added Chelsea's fourth to ensure the angry fans who booed Pochettino in the second half were silenced, at least for now.
For the sixth time in the last eight years, the Blues have advanced to the last four in the FA Cup. But this was hardly a triumphant afternoon for Blues boss Pochettino, whose inconsistent team blew the two-goal half-time lead given to them by Marc Cucurella and Cole Palmer.
