LONDON - Chelsea claimed partial revenge for their stormy loss to Manchester United at the weekend by prevailing 5-4 when the teams resumed hostilities in an end-to-end fourth-round League Cup tie on Wednesday.
United led three times at Stamford Bridge, but each time Chelsea responded, with Eden Hazard's 94th-minute penalty taking the game to extra time before goals from Daniel Sturridge and Ramires put the hosts in the quarter-finals.
There were shocks in the night's other ties, meanwhile, as Swansea City won 3-1 at Liverpool to knock former coach Brendan Rodgers out of the competition and Norwich City came from behind to eliminate Tottenham Hotspur.
United's controversial 3-2 win in the Premier League on Sunday ended with claims that referee Mark Clattenburg had abused Chelsea's John Mikel Obi.
United went ahead in the 22nd minute when Ryan Giggs coolly shaped a shot past Petr Cech.
The lead lasted only 11 minutes, David Luiz scoring from the penalty spot.
Javier Hernandez held his nerve to beat Cech as the visitors moved ahead.
Gary Cahill replied with a 52nd-minute header, but as Nani lofted the ball over Cech.
Further goals to Chelsea's Ramires, Hazard and Daniel pass, rounding Lindegaard, Sturridge sealed the game.
Giggs scored from the spot to take the incredible goal tally to nine.
