Liverpool increased the pressure on Everton boss Roberto Martinez with a dominant 4-0 victory in the Merseyside derby at Anfield last night.

After 42 goalless minutes Divock Origi and Mamadou Sakho found space in the Everton box to power home quickfire close-range headers, leaving the shell-shocked Toffees 2-0 down at the break.

Any hopes of a comeback evaporated when Ramiro Funes Mori was sent off for a stamp on Origi’s ankle, which also ended the Belgian’s involvement.

His replacement Daniel Sturridge put the Reds 3-0 up just after the hour and also had a partial claim on Philippe Coutinho’s strike 14 minutes from time.

“I would like to say yes, I am delighted, but the injury to Divock Origi has cost me some joy,” Liverpool manager said.

“They say it is disgusting, awful pictures. But it’s not broken, it is a twisted ankle, he is on crutchesso we will have to see.”

The result leaves Jurgen Klopp’s men in seventh, after both Manchester United and West Ham kept their top-four bids alive with wins.

Everton, who face Manchester United in the FA Cup semi-final on Saturday, are 11th, but morale will be at rock-bottom.

“It is a really hurtful experience,” he said.

“At the moment we are facing strong adversity but we have to switch attention to the big game at the weekend.”

United moved within a point of fourth-placed Arsenal with a 2-0 success over Crystal Palace at Old Trafford.

Right-back Matteo Darmian saw his cross turned over the line by Palace defender Damien Delaney in the fourth minute and went one better early in the second half when he controlled the ball on his chest and lashed home his first United goal.

The Hammers kept pace by seeing off a compliant Watford 3-1.

Andy Carroll continued his run of form with the opener in the 11th minute before Mark Noble converted a pair of penalties.

Sebastian Prodl pulled one back for the Hornets.
