Watch all the goals and highlights from this clash at Anfield.
In-form Liverpool enhanced their Premier League title challenge and closed to within a point of leaders Chelsea after overcoming a stubborn Sunderland side 2-1 at Anfield.
Steven Gerrard’s superb 39th-minute free-kick broke the deadlock and Daniel Sturridge doubled the hosts’ lead early in the second half, only for Ki Sung-yueng’s late header to leave Liverpool hanging on.
When the final whistle did come, to roars of relief from the home fans, it gave Brendan Rodgers’s side a seventh consecutive victory and took them above Manchester City, who retain two games in hand.
Sunderland, meanwhile, remain third from bottom, three points from safety, but with a game in hand on both of the two sides immediately above them.
While Liverpool were unchanged from their 6-3 win at Cardiff City, Sunderland coach Gus Poyet gambled by fielding a five-man defence in an attempt to blunt the hosts’ razor-sharp attack.
Liverpool’s team bus had been greeted outside the stadium by fans wielding flags and flares trailing red smoke, but Sunderland’s tactics initially enabled them to quieten the home crowd.
A succession of Liverpool attacks broke down on the edge of the box, obliging the hosts to chance their arm from distance, but Philippe Coutinho, Luis Suarez and Joe Allen all failed to find the target.
They needed a helping hand and shortly before half-time they got one, as Sunderland defender Santiago Vergini conceded a free-kick for an untidy foul on Suarez just outside the visitors’ box.
As the last man, the Argentine could have been shown a red card, but although he escaped with only a yellow, Gerrard punished his offence by arcing a glorious free-kick into the top-right corner from 22 yards.
In response, Connor Wickham saw a deflected shot saved by former Sunderland goalkeeper Simon Mignolet, but Sturridge’s strike three minutes into the second half gave Liverpool breathing space.
Henderson spread the ball wide to Sturridge on the right and the England man cut in before bending a left-shot past goalkeeper Vito Mannone via a deflection off Wes Brown.
It was Sturridge’s 20th goal of the season, making him and Suarez – nicknamed ‘the SAS’ in the British media – only the third duo to both score 20 goals or more in the English top flight since 1992.
The visitors looked there for the taking, but after Mannone had thwarted Suarez, Coutinho and Sturridge and Suarez had fizzed a shot wide, Lee Cattermole gave the hosts a scare by clattering a shot against the bar.
Remarkably, Sturridge did the same thing just a minute later at the other end, before Ki pulled a goal back with 14 minutes to play.
The South Korean stooped to head home from close range after a corner from fellow substitute Adam Johnson had been allowed to drift across the box, but Liverpool withstood a nervy finale to claim all three points.
