Man of the match - Adam Lallana
Lallana was Liverpool's creative spark and his two goals rounded off a superb individual display
Middlesbrough boss Aitor Karanka: "We have to remember how good we've been in the games before this, against Bournemouth and Hull City. I think they were the best team we've faced this season.
"We tried, especially in the second half with two new players, to press higher. It proved impossible to stop them. I can admit they were much better than us."
Middlesbrough 0-3 Liverpool: Reds were best we've faced - Aitor Karanka
Liverpool manager Jurgen Klopp: "We had moments in the first half where we were static and even I was confused. We did much better second half, we could have finished more often.
"Adam Lallana is improving even when he doesn't score, but it's nice he's in that situation. About a year ago I had sat him in the office and I was happy with him but he was like 'I'm not scoring' - and I said he wasn't in the right positions. Tonight he was twice in the right position and it was wonderful."
