Chelsea came from behind three times to beat Manchester United 5-4 after extra time and book a spot in the League Cup quarter-finals today, earning revenge for their controversial 3-2 league defeat.
Holders Liverpool were knocked out by boss Brendan Rodgers' former side Swansea City while Norwich City beat Tottenham Hotspur.
Another high-scoring thriller ensued at Stamford Bridge although both Alex Ferguson and Roberto Di Matteo elected to send out vastly different teams in the often maligned secondary cup competition.
United netted first through Ryan Giggs before David Luiz scored for Chelsea from the penalty spot.
Javier Hernandez took the lead back for United after another defensive mistake, before defender Gary Cahill again levelled matters on 52 minutes.
United again went infront just before the hour mark thanks to Nani's cool chip, but another penalty, this time from substitute Eden Hazard, sent the match into extra time.
Daniel Sturridge, who had missed a host of chances throughout, nabbed Chelsea's fourth by latching onto a poor backpass and there was even time for a Ramires goal and a Giggs penalty.
Liverpool boss Rodgers, who left Swansea in the close season, saw the Welsh side win 3-1 at Anfield to humiliate his stuttering side.
Chico grabbed the opener for Swansea in the 34th minute as Liverpool also played a much changed side with forgotten man Joe Cole getting a rare look-in but failing to impress.
The weakened hosts went 2-0 down midway through the second half through Nathan Dyer before substitute Luis Suarez pulled one back and Jonathan de Guzman sealed Swansea's first ever League Cup quarter-final spot late on.
Norwich will also be in the last eight after coming from behind to beat Tottenham 2-1 at home with Simeon Jackson grabbing the 87th minute winner.
