In the evening's marquee fixture, Chelsea knocked out Premier League leaders Arsenal and advanced to the quarter-finals with a 2-0 triumph at the Emirates Stadium.
Chelsea showed no ill-effects from playing just two days earlier, despite manager Jose Mourinho's complaints about the fixture list.
Both managers selected largely second-choice squads, with striker Nicklas Bendtner making a rare start for Arsenal and Juan Mata returning to Chelsea's first XI.
Chelsea went ahead in the 24th minute following a defensive mistake by Arsenal.
In an incident reminiscent of Chelsea's late winner against Manchester City at the weekend, Arsenal's Carl Jenkinson directed a lazy header toward goalkeeper Lukasz Fabianski.
But Chelsea's Cesar Azpilicueta beat Fabianski to the ball and finished skilfully at the far post with his first touch.
Arsenal pressed for the equaliser in the second half, with manager Arsene Wenger introducing Mesut Ozil in the 63rd minute. But Chelsea struck again just three minutes later through Juan Mata's powerful drive.
Wenger then sent on striker Olivier Giroud in search of an unlikely comeback, but the hosts could not find the back of the net as Mourinho claimed yet another win over his old rival Wenger.
On target: 1-3
Manchester United eased into the last eight with a 4-0 home win over fellow Premier League side Norwich City at Old Trafford.
Two goals came courtesy of Mexico international forward Javier Hernandez, who continued his fine run of form in the competition.
Hernandez put United ahead with a 20th-minute penalty after Leroy Fer brought down Adnan Januzaj in the box. He added the second as well, heading into the net in the 53rd minute after Mark Bunn stopped his initial attempt.

Phil Jones added the third in the 85th minute, his first goal in 56 games for United, before Fabio made it 4-0 deep into stoppage time.
United's starting XI also featured youngsters Januzaj, Wilfried Zaha and Alexander Buttner. Anders Lindegaard started in goal in place of David De Gea, while Rio Ferdinand and Nemanja Vidic formed the central-defensive partnership.
Burnley 0-2 West Ham
Matthew Taylor scored the opener for West Ham in the 75th minute.
Jack Collison made it 2-0 in stoppage time after Burnley had Keith Treacy sent off.
Leicester City 4-3 Fulham
Championship side Leicester City knocked out Premier League strugglers Fulham in an exciting match at the King Power Stadium.
Goals from Wes Morgan, Chris Wood and Ignasi Miquel gave Leicester a 3-1 lead early in the second half after Hugo Rodallega had put the visitors ahead. Moments after Miquel's goal, though, Rodallega pulled one back for Fulham, who then equalised via Giorgos Karagounis three minutes from time.
But Leicester grabbed the win with Lloyd Dyer's 89th-minute goal.
Birmingham 4-4 Stoke (a.e.t., 2-4 on penalties)
Stoke survived a scare at Birmingham, winning the penalty shootout 4-2 after a thrilling 120-minute draw at St. Andrews.
Birmingham thrice pegged back Stoke after the Potters had taken leads of 1-0, 3-1 and, in extra time, 4-3.
Tom Adeyemi (28'), Peter Lovenkrands (84', 90') and Oliver Lee (117') scored for Birmingham. Oussama Assaidi (10'), Peter Crouch (55'), Marko Arnautovic (71') and Kenwyne Jones (93') scored for Stoke.
Birmingham had Wade Elliott sent off in first-half stoppage time.
Tottenham Hotspur 2-2 Hull City (a.e.t., Spurs win 8-7 on penalties)
Tottenham survived a scare against Premier League rivals Hull City, winning a penalty shootout 8-7 following a 2-2 draw after extra time.
The teams were tied 1-1 after 90 minutes. Gylfi Sigurdsson put Spurs ahead with a powerful finish in the 16th minute, but Hull equalised via a Brad Friedel own goal early in the second half.
Paul McShane put Hull ahead in the 99th minute, only for Spurs to draw level via Harry Kane nine minutes later.
Newcastle United 0-2 Manchester City (a.e.t.)
Alvaro Negredo and Edin Dzeko scored in extra time as Manchester City passed a test at Newcastle United.
The teams were tied 0-0 after 90 minutes.
Costel Pantilimon kept a clean sheet for City, giving manager Manuel Pellegrini food for thought following Joe Hart's error at the weekend.
Here is the fifth-round draw. Sunderland and Southampton will play their fourth-round match Nov. 6.
