Liverpool blew the Gunners away 5-1.
"There are triggers when to go and press the ball and you need tactical discipline from everyone," explains Rodgers. "A club like Barcelona teach it from their youth teams, so when young players make the first team they already know all the triggers. It took time to introduce it here but the players all listened.
"The reference (when to press) is in relation to who has got the ball, which opponent. You might have a right-footer like (Arsenal defender Laurent) Koscielny playing on the left side so you could highlight him.
"You let him have the ball and as soon as he has it, you jump, you press, you know what his passing line is going to be, so you set up your winger to press on the next one. The midfield follow up. They are all links in a chain.
"The game against Arsenal was a beautiful game as a coach. I was very proud to watch the team because that's what you work on. To hear some of the former players like John Barnes and John Aldridge, who come from a time when Liverpool were in their pomp, talking about the best part of a game they have ever seen - that really tells you the level the team is at."
