Football: Liverpool demolish Crystal Palace to extend Premier League lead

Liverpool's Roberto Firmino and Mohamed Salah each netted twice in a scoring masterclass as the visitors thrashed Crystal Palace 7-0 to record their first away win in the Premier League since September and move a provisional five points clear at the top.

It marked the first time the Reds had won away in the top-flight by a margin of seven goals and was their biggest league victory since they hammered Palace 9-0 at Anfield in 1989, when they won the old top-flight First Division title.

The result put the defending champions on 31 points after 14 games ahead of second-placed Tottenham Hotspur, who host Leicester City on Monday (NZ time).

Japanese midfielder Takumi Minamino repaid Juergen Klopp's decision to start him instead of Mohamed Salah by scoring after just over two minutes and Sadio Mane then made it two when he twisted and fired home from the edge of the box in the 35th.

Firmino added a third just before the break, flicking home to finish off a glorious Liverpool counter-attack that swept the length of the field, and Jordan Henderson added a fourth seven minutes into the second half as Palace fell apart.

Firmino got his second with a brilliant chipped effort in the 68th and Salah came on to net with a header before superbly curling a shot into the top corner five minutes from time.

Henderson praised his side's efforts in front of goal but, despite the dominant display and the margin of victory, the midfielder said his side could still improve.

"I thought we were ruthless today and took our chances which is always important. We dominated the game for large periods but I still thought we were sloppy at times," he told BT Sport.

"Overall, the performance level, we have to be happy. Now we have a week leading to the next game. Then another tough test again," he added ahead of the visit of West Bromwich Albion.

Arsenal's dreadful Premier League season has continued with a 2-1 defeat to resurgent Everton at Goodison Park leaving the Gunners five points above the relegation zone.

Everton, who move up to second place, took the lead in the 22nd minute when an Alex Iwobi cross was met with a header from Dominic Calvert-Lewin which flew in via a deflection from Arsenal defender Rob Holding.

Mikel Arteta's side drew level, against his former club, through a Nicolas Pepe penalty in the 35th minute, awarded after a Tom Davies foul on Ainsley Maitland-Niles.

But the Toffees restored their advantage on the stroke of halftime when Yerry Mina timed his run to perfection to angle in a near post header from a Gylfi Sigurdsson corner.

Meanwhile, Manchester City has closed the gap on the Premier League top four after Raheem Sterling's first-half goal proved enough to secure a hard-fought 1-0 victory over Southampton at St Mary's.

After a spell of constant pressure, City broke the deadlock in the 16th minute when playmaker Kevin De Bruyne's cross from the right wing found Sterling, who slotted the ball past Saints goalkeeper Alex McCarthy.
