Full time: Middlesbrough 0-3 Liverpool
Perhaps as routine a win as you'll see from any Premier League team this season. Jurgen Klopp's men go second ahead of the Merseyside derby after goals from Adam Lallana either side of Divock Origi's fifth goal in as many games secured the most comfortable of victories. For Middlesbrough, they drop to 17th and are three points off the relegation zone. Aitor Karanka needs to think again.
Three minutes added on at the Riverside. Trent Alexander-Arnold on for his Premier League debut for Liverpool.
Divock Origi down for Liverpool. Is their ideal evening about to be soured?
Chants of 'for the 96, justice' ring out from the Liverpool end at the Riverside, a song which is greeted by a round of applause from the Middlesbrough fans. Very pleasant between both sets of fans, but that is as close as it has been tonight.
The visitors celebrate extending their lead at the Riverside.
Goal: Middlesbrough 0-3 Liverpool (Adam Lallana)
Jurgen Klopp's side have been complete dominant in this second half and they get a third which as things stand will be enough to put them second. Mane feeds Origi, whose cross finds the unmarked Lallana who strokes into the net. Too, too easy.
Credit to Middlesbrough, they've had a go at Liverpool since conceding what should be a fatal second goal. It was at this stage a few weeks ago that Klopp's men started to unravel at Bournemouth. Another test of their metal on the way.
Goal: Middlesbrough 0-2 Liverpool (Divock Origi)
Right on cue Liverpool get there second and you would be tempted to say that should secure the points. The Reds win the ball back in the Middlesbrough half and after Mane and Wijnaldum exchange passes, Lallana feeds Origi who sweeps home first time beyond Valdes, for his fifth goal in as many games.
Liverpool are simply pouring players forward in search of a second goal. They're regularly outnumbering Middlesbrough in the final third but yet this ambition is has not been rewarded with a second goal. Karanka has introduced Downing and Leadbitter in an attempt to stem the tide but as yet they are yet to regain any sort of control in this game.
The Senegal forward Mane is posing a threat every time he gets near the ball and once again he has the chance to double Liverpool's lead but his close range effort is smothered by the Middlesbrough defence.
Underway in the second half at the Riverside. No changes to either team but almost a change to the scoreline as Mane goes through on goal again but is denied by Valdes. Liverpool have made a fast start.
Half time: Middlesbrough 0-1 Liverpool
Routine so far for Liverpool who lead through Adam Lallana's header, and it could have been more in truth. Middlesbrough have huffed and puffed but rarely tested Simon Mignolet, while the Reds have been clinical and should be two up by Sadio Mane struck the post. Aitor Karanka has work to do at half time.
Adam Lallana celebrates scoring his fifth goal of the season to give Liverpool a half-time lead.
Liverpool almost double their lead. Sadio Mane goes through, beats Ben Gibson and Victor Valdes but is denied by the post, before Divock Origi hits the rebound into the side-netting.
Dejan Lovren puts everything on the line to keep Middlesbrough from drawing level, blocking Adam Clayton's effort with his face - a shot which sends him tumbling backwards.
More on this story as we get it. Worrying news from the Riverside.
Viktor Fischer forces a good near-post save out of Simon Mignolet as Middlesbrough look to bite back straight away. the hosts have been decent so far, working hard to nullify Liverpool but for how long can they keep this up?
Goal: Middlesbrough 0-1 Liverpool (Adam Lallana)
The breakthrough at last at the Riverside. Liverpool change the approach of the attack with a crossfield ball from Mane, which finds Clyne. The former Palace full-back cross terrifically to the back post where Lallana is waiting and he powers a head low past Valdes.
Tasty, competitive, lively. This game is ticking all of those boxes but excitement is certainly not one of them. Nothing in the way of chances for both teams in the opening 22 minutes, with even Simon Mignolet a spectator.
As you may have guessed, not exactly a action packed start to proceedings at the Riverside. Plenty of blood and thunder, particularly from the hosts, but nothing in the way of chances.
Underway in the north east. All eyes on Simon Mignolet in the early minutes.
Players are out at the Riverside. These fans in the north east have been waiting seven years for games of this enormity. Can they give Liverpool a bloody nose?
