Jurgen Klopp's side are currently unbeaten in nine Premier League games and have dazzled at times with their free-flowing attacking football.
However, the 'Reds' have also come in for criticism, with many seeing them as having a soft underbelly that can easily be exploited by opposition sides.
Not that Robertson buys into any of that. The former Hull City defender, who has started Liverpool's last four Premier League games, is confident that the club are starting to find the right balance between their undoubted attacking prowess and a certain defensive solidity.
"Going forward it is a joy to watch. It's frightening at times the pace that we break at," he enthused.
"Everyone talks about the attacking, rightly so with the number of goals that we have scored, but in the last good few games defensively we have been solid and kept clean sheets.
"That's the basis for all the boys going forward. They put in a shift coming back (defensively) and that is what you need. We need to attack as a team and defend like a team.
"I think we have been good at that especially the last couple of weeks and if we continue to do that then we know the (attacking players) will come up with some brilliance.
"Everyone saw the four goals we scored at the weekend (against Bournemouth) and they were all high in quality."
Liverpool have improved immensely at the back in recent weeks, conceding just four goals in their last nine games and Robertson believes that their hard work on the training ground is finally paying off.
"I think it was just a case of going back to basics," he said.
"Get your formation behind the ball and when it is there to press then we need to go and press it. At the end of the day if we have got the ball then they can't score. We have been really good at that the past couple of games.
"We have been pressing them high up, we have been winning the ball in dangerous areas for them. When we nick it we only have 20 yards to go to their goal and we can create chances.
"When Simon (Mignolet) has been called upon he has made some good saves. We have been resolute to try and stop their chances and danger men.
"We have just got to try and keep doing that and not rest on our laurels. If we can keep earning clean sheets then we have always got goals in this team.
"It might not always be three or four goals a game but as long as we keep a clean sheet one is enough."
Finally, Robertson warned fans against expecting a goal-fest on Friday night, insisting that he expects a tight game against the 'Gunners'.
"They (Arsenal) are open, they play expansive football and have got world-class players as well going forward," he said.
"They are probably similar to us which is why the games have been so high scoring. But they have been working on their defensive (structure), they have kept cleans sheets so they have been more solid.
"We are expecting a tight game. We are right next to each other in the table so it's a good game for us before Christmas and we will be looking to take all three points."
