Chelsea 1-1 Newcastle (4-2 pens) - Highlights
Chelsea came back from the brink to reach the League Cup semi-finals with a dramatic penalty shoot-out victory against Newcastle after Mykhailo Mudryk's last-gasp equaliser.
Mauricio Pochettino's side were joined in the semi-finals by Fulham, who beat Everton on penalties, and second-tier Middlesbrough, 3-0 winners against Port Vale.
Beaten three times in their previous five games, a wretched run that started with their 4-1 loss at Newcastle, Chelsea showed some much needed fighting spirit to win the quarter-final 4-2 on penalties after a 1-1 draw at Stamford Bridge.
Languishing in 11th place in the Premier League, they were two minutes from being knocked out before Ukraine winger Mudryk came to the rescue with the leveller that set the stage for the Blues' shoot-out success.

Newcastle had been gifted the lead by Chelsea's shambolic defending in the 16th minute.

Two minutes into stoppage time, Chelsea forced a shoot-out as Newcastle defender Kieran Trippier made a hash of dealing with a cross, misdirecting his header to Mudryk, who drilled into the bottom corner.
