Title challengers Chelsea and Manchester City won this weekend to keep pace at the top of the Premier League. But that was far from the only action in England's top flight this weekend.
Manchester United, losers of three straight matches in all competitions, hosted Swansea City for the second time in less than a week. At the bottom of the table, Cardiff hosted West Ham in a match that could have significant bearing on this season's relegation race.
In the following slides, we take a closer look at all the matches.

Edin Dzeko and Alvaro Negredo scored in either half as Manchester City returned to the top of the table with a controversy-filled 2-0 win at Newcastle United on Sunday.
City broke through in the eighth minute as Dzeko converted following a flowing team move. David Silva picked out Aleksandar Kolarov with a clever through ball, and Kolarov crossed into the middle for Dzeko, who finished with his first touch.
Newcastle thought they had equalised through Cheick Tiote, whose outstanding long-range rocket beat Joe Hart from outside the box. Referee Mike Jones, however, disallowed the goal, ruling Yoan Gouffran offside.
The decision incensed Newcastle, who had the better of play for the rest of the first half. But Manchester City held on and clinched the points with Negredo's goal in second-half stoppage time.
Bursting free behind Newcastle's defence, Negredo had his initial shot stopped by Tim Krul. But Negredo ran onto the rebound and finished into the empty net to seal the three points.
City's Samir Nasri sustained a potentially serious knee injury in the second half after being tackled by Mapou Yanga-Mbiwa. Yanga-Mbiwa received a yellow card for the foul.

Luis Suarez scored twice and set up another as Liverpool returned to the Premier League's top four with a thrilling 5-3 victory at Stoke City on Sunday.
Daniel Sturridge produced a fine performance in his return from injury, scoring once and assisting another in a 24-minute substitute's cameo. Steven Gerrard also scored from the penalty spot for Liverpool, who moved into fourth place on 42 points with the win.
Peter Crouch, Charlie Adam and Jonathan Walters scored once each, and Marko Arnautovic added two assists, for Stoke. The Potters remained 12th with 22 points.
The eight-goal cracker featured four goals in each half, multiple defensive errors and a two-goal, first-half comeback. Liverpool had never previously won at Stoke in the Premier League.
Liverpool took an early 2-0 lead through an own goal and Suarez's opportunistic finish before Crouch and Adam—both former Liverpool players—replied with goals late in the first half. The visitors then established another two-goal advantage in the second half before Stoke briefly pulled it back to 4-3. Sturridge sealed the points with a late goal.
On target: 4-9
Manchester United won for the first time in 2014, turning a strong second-half performance into a 2-0 victory at home to Swansea City on Saturday in the Premier League.
Antonio Valencia and Danny Welbeck scored in the second half for United, who ended a three-match losing run and avenged last weekend's FA Cup defeat at the hands of this same Swansea side. With the victory, seventh-placed United moved onto 37 points, two behind Liverpool, who play Sunday.
The match was goalless at half-time, but just over a minute after the restart, United were ahead.
The hosts laid siege to Swansea's box as soon as the half started, Kagawa forcing a save from Tremmel with a powerful header from Januzaj's cross. Valencia pounced on the rebound and swept in for a 1-0 United lead in the 47th minute.
United made it 2-0 in the 59th minute after the visitors failed to properly clear Januzaj's cross. As the ball rolled out, Patrice Evra sent it back into the middle of the box, where Welbeck used the outside of his boot to redirect into the net.
A scheduling quirk meant Saturday's meeting was the second between United and Swansea at the same venue in less than a week. The same teams played last weekend in the third round of the FA Cup, with Swansea winning 2-1 at Old Trafford.
Heading into Saturday's rematch, United had lost three straight games in all competitions. The Red Devils last lost four straight matches in 1961.
On target: 5-2
Chelsea moved to the top of the table, at least temporarily, with a 2-0 win at Hull City in Saturday's early kickoff.
The win put Chelsea on 46 points, one ahead of Arsenal and two ahead of Manchester City. Arsenal play at Aston Villa on Monday, and City play at Newcastle on Sunday.
The Blues were not at their best, but the opening goal came from a fine piece of team play.
Receiving the ball on Chelsea's left side near Hull's box in the 56th minute, Ashley Cole unlocked the hosts' defence with a clever back-flick to Hazard. Hazard glided into the middle along the edge of the box, faked a shot and then finished into the bottom corner with an inch-perfect low shot.
According to Premier League on Twitter, Chelsea manager Jose Mourinho said of Hazard: "Every manager wants players like him. You are watching a much more mature player with much more responsibility."
Torres sealed the victory in the 87th minute, accepting a pass from Willian before running at the Hull defence and finishing at the near post.
Chelsea goalkeeper Petr Cech kept his 209th clean sheet, a club record per @ChelseaFC.

Carlton Cole and Mark Noble scored the goals as West Ham picked up a precious 2-0 victory at fellow strugglers Cardiff City on Saturday.
With the three points, West Ham moved into 17th place and out of the relegation zone on 18 points, one place ahead of Cardiff on goal differential. The win came at the end of a difficult week for the Hammers, who lost 5-0 at Nottingham Forest last weekend in the FA Cup and 6-0 at Manchester City this week in the Capital One Cup.
West Ham defender Guy Demel suffered a frightening injury in the eighth minute after colliding with teammate Roger Johnson in the Hammers' box. Replays showed Johnson's arm making contact with Demel's face before Demel landed awkwardly on his left arm.
Demel left the pitch on a stretcher following a nine-minute delay. Per BBCSport on Twitter, Demel suffered a broken elbow and facial injuries.
Cole broke the deadlock in the 42nd minute, turning in Matthew Jarvis' cross from the right.
The Hammers went down to 10 men in the 72nd minute, when James Tomkins was sent off for his second yellow card. He drew the second booking for a high challenge on Cardiff's Fraizer Campbell.
It didn't matter, though, as the visitors extended their lead in stoppage time via Noble. Substitute Andy Carroll, making his first league appearance since May 2013, provided the assist.

Everton moved into the top four, at least for the moment, with a 2-0 victory at home to strugglers Norwich City.
Gareth Barry and Kevin Mirallas scored in either half as the Toffees leapfrogged rivals Liverpool into fourth place, pending the result of Liverpool's match at Stoke on Sunday.
Barry opened the scoring in the 23rd minute, guiding a long-distance screamer into the top corner at the far post. It was his 50th Premier League goal.
Mirallas doubled Everton's lead with a well-taken free kick in the 59th minute. Norwich had chances to score—Robert Snodgrass hit the woodwork with a header—but were unable to find a consolation goal.
With the win, Everton moved onto 41 points, two ahead of Liverpool for the moment. Norwich remained 15th, two points above the relegation places.
Before the match, Everton unveiled new signing Aiden McGeady. The Toffees signed the former Celtic winger from Spartak Moscow.

Adam Johnson scored his first career hat-trick to lead Sunderland to a 4-1 win at Fulham on Saturday.
Johnson broke the deadlock with a well-taken free kick in the 29th minute. With Sunderland holding a delicate 2-1 lead in the 69th minute, he scored his second, converting Ki Sung-Yueng's angled through ball.
Johnson completed his hat-trick with a penalty in the 85th minute, after Philippe Senderos was adjudged to have fouled Jozy Altidore in the Fulham box.
Ki scored Sunderland's other goal, making it 2-0 in the 41st minute. Steve Sidwell scored Fulham's lone goal in the 52nd minute.
The win took Sunderland onto 17 points. The Black Cats remain in the relegation zone but are now only one point adrift of safety. Fulham are 16th, one point clear of the relegation zone.
On target: 5-6
Adam Lallana scored the lone goal as Southampton won 1-0 at home to West Brom on Saturday.
The victory was only the second in 10 matches for the Saints, who are ninth with 30 points. West Brom are 14th with 21 points.
Lallana broke the deadlock in the 66th minute, latching onto substitute Gaston Ramirez's fine flick before finishing past Ben Foster.
Southampton goalkeeper Artur Boruc saved Shane Long's close-range shot in the closing minutes to preserve the victory.
New West Brom manager Pepe Mel watched the match from the stands. Mel was appointed this week to replace the sacked Steve Clarke.

Tottenham Hotspur won 2-0 at home to Crystal Palace on Saturday to move up to fifth.
Christian Eriksen and Jermain Defoe scored the goals for Spurs, who won for the third straight outing and remained unbeaten in the league under Tim Sherwood.
Crystal Palace started brightly and won a penalty in the eighth minute, when Mousa Dembele brought down Marouane Chamakh in the Tottenham box. But from the resulting spot-kick, Jason Puncheon blasted his shot well high and wide, keeping the match goalless.
Spurs went ahead in the 50th minute. Moments after entering as a substitute, Kyle Naughton played a long pass forward from Tottenham's half. Emmanuel Adebayor headed down for Eriksen, who steadied himself with a touch before finishing high at the near post.
Substitute Jermain Defoe doubled Spurs' lead in the 72nd minute, keeping his head under pressure in the box to fire past Julian Speroni. Tottenham confirmed this week that Defoe will join Major League Soccer club Toronto FC at the end of February.
The win sent Spurs into fifth place on 40 points. Sixth-placed Liverpool play at Stoke on Sunday. Crystal Palace are 20th with 17 points.

Jack Wilshere scored a goal and assisted the other as Arsenal returned to the top of the Premier League table with a 2-1 win at Aston Villa on Monday night.
Olivier Giroud also scored for the Gunners, who led 2-0 at half-time on the way to their eighth win in 11 away matches this season.
Aston Villa's Christian Benteke ended a personal goal drought that had spanned 11 league matches, scoring in the second-half to set up a tense finish.
The victory moved Arsenal onto 48 points through 21 matches, one point more than Manchester City and two more than Chelsea. Both City and Chelsea won at the weekend, placing pressure on Arsenal to take the full three points at Villa Park.
