He told liverpoolfc.com: "The more and more I'm playing in the middle of the pitch, the more pressure and the more tight and compact I find it. So I think the manager has told me and the team to drop out of the block, try to get on the ball and get up the field that way, whether it's driving with the ball or passing it over the top. It's just trying to get on the ball as much as possible and trying to make things happen from deep and create.
"There has to be discipline in there, and it's not just me who has the freedom to go in there and do that. The rest of the team have to move around, adjust and make sure we are in a good position to go and win the ball back and make sure we are still protected and not exposed if we lose the ball. But within that there is then freedom and space to get on the ball, make things happen and get us up the pitch essentially.
"At this point of the season, we have nothing to lose as a team. We need to try to get goals as well, we need to chase goal difference. We scored three goals today, which is a positive. It's a big week now for us to go and push on, and we've built a good foundation after a tough week."
Liverpool next meet Everton in Wednesday's Merseyside derby against Everton at Goodison Park.
Alexander-Arnold also said: "Already, to be honest! It's exciting. When it comes to derbies, football kind of goes out the window, and it's about who wants to win it more. They'll be looking to put an end to our title race and any chance of winning the title this year, and we'll be looking to put them in a sticky situation as well.
"It's going to come down to who wants it more. They've got a good result today, we've got a good result. It's two teams that are in decent form, so I'm sure it'll be a very, very good game."
