For much of Tuesday's quarter-final clash, the Magpies seemed destined for the last four, safeguarding a 16th-minute lead until the fifth minute of injury time. Callum Wilson capitalised on Benoit Badiashile's error, putting the visitors ahead on Tuesday evening at Stamford Bridge.
However, the Toon Army's joy turned to despair when Trippier's error allowed Mudryk to nip in and equalise. The defender's nightmarish sequence continued as he missed a penalty in the eventual shootout, while Mudryk converted, paving the way for a much-needed victory by a 4-2 margin for Mauricio Pochettino's side.
