Man Utd 0-3 Liverpool: What Slot said
Liverpool boss Arne Slot, speaking to Sky Sports: "The first few minutes, United started aggressive and we had to fight our way through the period.
"If you go to Old Trafford we know there will be tough moments. After scoring a great goal which was disallowed we kept on playing as we were before. A deserved win I think.
"There is not a specific game-plan from the back, we always want to press the opponent high. The game-plan - Dominik [Szoboszlai] played from the right, but today we played him from the left.
"Last season Man Utd were man-marking on the midfield, this season they are on a nine and ten press with a 4-4-2. In my opinion they are working harder when the ball is played through them so they run more - that is what I saw in the first games from them.
"Today we showed a lot of moments where the forwards tracked back so aggressively and that is what we need if you want to win these games."
On the message at half-time: "We said they were going to press aggressively, but I showed them three moments where one situation that led to a chance for Mazraoui.
"Luis [Diaz] was not tracking back as he should. Those moments can change the game at Old Trafford.
"It's a good win."
