Adam Lallana scored twice and created another goal to give Liverpool their most emphatic away Premier League win of the season in a dominant display at Middlesbrough.
The Reds arrived at the Riverside Stadium having taken just one point from their past two matches and manager Jurgen Klopp chose to drop goalkeeper Loris Karius.
However, his replacement Simon Mignolet had little to do after Lallana headed home Nathaniel Clyne’s cross before the break as Liverpool seized complete control.
Sadio Mane wasted several opportunities but Lallana was clinical, first crossing slickly for Divock Origi to prod home a fine team goal, then side-footing in a pass from the Belgium striker for the third.
The three-goal margin was enough to move Liverpool second, while Boro – competitive in the first half but abject after the break – drop to 17th.
The gulf in class between these two teams was clear. Often keeping possession with 10 home shirts behind the ball, Liverpool waited for key moments to inject pace into attacks with devastating effect.
Klopp’s decision to replace Karius drew focus before kick-off, but that will switch to his side’s qualities after this display.
Lallana was at the centre of everything they did well. Shortly after arriving at the back post to head home the opener, he slid in to block a stinging Adam Forshaw shot at the other end.
Mane struck the woodwork, giving the hosts hope in the second half, but a one-touch interchange involving the Senegal international, Georginio Wijnaldum, Lallana and Origi for the second goal epitomised all that was good about the classy visitors.
