Liverpool handled the increasing pressure well at the Olympic Stadium with a comprehensive demolition of West Ham United.
Daniel Sturridge scored the opener in his first league start since the beginning of January before Phil Coutinho added two quick goals - with Origi firing in a 4th.
The reds made two changes for this game, with Adam Lallana ready to make his first start in almost 2 months and Daniel Sturridge in for the injured Roberto Firmino. Phil Coutinho slotted into a more central position with Lucas Leiva out of the side.
In the bright afternoon sunshine, the reds and West Ham traded early blows - with Joel Matip going closest when he headed downwards from a corner.
Liverpool's goal arrived after a number of chances - Coutinho in his own half feeding a magnificent through ball which Sturridge latched on to. The England striker rounded the keeper before scoring only his 3rd league goal of the year.
As half time approached however the reds had a huge let off. They failed to deal with a corner that went right to the back post but Andre Ayew could only find the post from 2 yards out.
The second half and the reds raced out of the traps, chances for Origi and Wijnaldum within the first 60 seconds.
It was Coutinho who doubled the reds lead and eased the pressure. Wijnaldum fired a powerful shot that bounced back off the bar and after a little dribble at the edge of the box, Coutinho fired in.
Moments later he increased the reds lead further. From a West Ham corner the reds broke quickly as West Ham appealed for a foul in the area, and the ball was fed into the Brazilian's path - he cooly fired in to ensure all 3 points would be returning back with the reds.
There was still time for another goal and it arrived for Divock Origi.
Daniel Sturridge twisted at the right hand side of the box, and fed the ball into the area. The West Ham keeper, Adrian, rushed out to prevent Lallana scoring but the ball bobbled into the path of Origi who passed it into the corner of the net.
A beaming Klopp gave Sturridge a trademark hug when the Liverpool striker was substituted. The reds need to win their final home game next weekend to be certain of finishing inside the top four for only the second time in 8 years.
