Jensen saved from captain Wayne Bridge and John Mikel Obi to put Burnley into the quarter-finals with a 5-4 shootout win following a 1-1 draw after extra-time.

Returning striker Didier Drogba put Chelsea in front in the 27th minute but Burnley substitute Ade Akinbiyi equalised with 20 minutes remaining.

Both sides ended the game with 10 men after Burnley's Steve Caldwell was sent off for a second bookable offence late on, while Franco Di Santo was forced off injured with all Chelsea's substitutes already used.

But Jensen sparked scenes of celebration when he saved Obi's sudden-death spot-kick to put the second-tier side into the last eight.

Tottenham Hotspur manager Harry Redknapp's magic touch continued at White Hart Lane with the North Londoners recording a thumping 4-2 victory over Liverpool to secure a place in the quarter-finals alongside Burnley.

As if to illustrate the manager's impact since taking charge 18 days ago, it was two players on the fringes during Redknapp's revolution who turned the tie with three goals in six minutes just before the break against Rafael Benitez's reserves.

Roman Pavlyuchenko, who netted the late winner when Liverpool were beaten by Spurs in the Premier League recently, opened the scoring with a crisp finish before Fraizer Campbell added his first two for the club since his loan from Manchester United.

Damien Plessis and Sami Hyypia pulled goals back on either side of Pavlyuchenko's second but Spurs held on to stay in the competition they won in February under Juande Ramos.

Blackburn Rovers striker Roque Santa Cruz needed just two minutes to announce his return in style as his team also booked its place in the Carling Cup quarter-finals with a 2-1 win at Sunderland.

The Paraguayan headed Rovers in front with 65 minutes gone after replacing teenager Andy Howarth and then saw Phil Bardsley put through his own goal five minutes later.

Kenwyne Jones, a surprise inclusion for the Black Cats after he was sent to see a specialist over his knee injury just a day before the match, gave the home side hope with his first goal of the season seconds later.

But the visitors saw the game out to condemn the Wearsiders to a fourth successive defeat in front of a crowd of just 18,555.
