Manchester United deepened Liverpool's January gloom as Bruno Fernandes's pinpoint free kick earned his side a 3-2 win in a blockbuster FA Cup fourth-round clash at Old Trafford on Sunday.
The Portuguese, on as a substitute, stepped up to bend a right-footed strike beyond Liverpool keeper Alisson in the 78th minute to book a last-16 tie for his side against West Ham United.
Leicester City, fancied to go all the way, struck three times in the second half to win 3-1 at Championship side Brentford, while Tammy Abraham's hat-trick gave Chelsea a 3-1 victory at home to second-tier Luton Town at snowy Stamford Bridge to ease some of the pressure on Frank Lampard.
Burnley won 3-0 away to Fulham.
A week after Liverpool and United's turgid 0-0 stalemate in the Premier League at Anfield, the north west rivals served up a Cup classic full of attacking football.
Mohamed Salah scored both of Liverpool's goals, the first to give his side an 18th-minute lead before Mason Greenwood levelled, and then again in the 58th minute after the outstanding Marcus Rashford had slotted United ahead.
A much-improved Liverpool looked the more likely winners but it was Fernandes, so often United's attacking spark, who sealed it with his 28th goal for them since his debut last February.
"When you leave him out like I did today, he stayed about 45 minutes after training yesterday shooting free kicks so I was pretty confident he could score one if he got the chance," United boss Ole Gunnar Solskjaer, whose side have lost only once since crashing out of the Champions League in early December, said.
Liverpool have now won only once in seven games, although at least this display was more recognisable to the side that romped away to the English title last season.
"We can take things out of this game, we try to learn from every game. It's good for Mo Salah, good for the confidence. It was a tough game," manager Juergen Klopp said.
