Liverpool remain in charge at the top of the Premier League, as they beat bitter rivals Manchester United 3-1 at Anfield on Sunday.
After a frantic start, the breakthrough eventually came in the 24th minute – Mane losing his marker and coolly slotting past David de Gea after bringing Fabinho’s incisive pass down on his chest.
But United were handed an early Christmas present as Alisson spilled Romelu Lukaku’s simple cross from the left, allowing Lingard to turn the ball home with ease from close range.
Meanwhile, Paul Pogba remained an unused substitute on United’s bench, Jose Mourinho opting to bring on Marouane Fellaini at the interval with his side short of inspiration.
Liverpool nearly regained their lead shortly after the break as Firmino danced his way through the United defence, only to see his poked effort turned away low by De Gea, and though the visitors forced a few attacks, Liverpool did eventually get their second.
Shaqiri was not to be denied, as he found the net via the crossbar and a deflection off Ashley Young following Mane’s cut-back.
He completed the win 10 minutes from the end, his 20-yard strike flicking off Eric Bailly to send Liverpool back to the top.
There was an element of good fortune about both of the Swiss international’s goals, but one cannot begrudge Liverpool their victory against this desperately ordinary United side.
Next Liverpool travel to Molineux to play Wolves on Friday, 21 December (20:00 GMT), while Manchester United play away at Cardiff the following day (17:30).
