Liverpool moved into second place in the Premier League table, above Arsenal on goal difference, after a comfortable 3-0 win over Middlesbrough at the Riverside Stadium.
Aitor Karanka’s side conceded three goals in a home game for the first time in almost two and a half years – underlining the impressive nature of this win.
Lallana’s opener put the Reds ahead during an even first half in which Simon Mignolet was a reassuring presence in goal after Jurgen Klopp axed the jittery Loris Karius.
Liverpool then made sure that Klopp’s selection was justified with an electric second-half performance, scoring a pair of exceptionally worked goals to pull clear.
While Klopp’s men are on the up again, Boro are just three points above the relegation zone after back-to-back scoreless defeats.
