The Scot has featured in three games for the Reds since his summer switch from Hull City – a win over Crystal Palace, draw with Burnley and defeat to Leicester City.
Robertson performed impressively in each of those outings, but has otherwise seen his opportunities limited by the form of fellow left-back Alberto Moreno.
However, the 23-year-old retains a belief that he can make a bigger impact as the season progresses and will keep fighting for his chance to do so.
He told Liverpoolfc.com: “If you’re sitting on the bench or sitting in the stand then you have to believe that you can change things.
“Even against Arsenal, I thought they were magnificent, to a man they were different class, but if you’re not in the team you’ve got to be thinking I can perform like that if I’m in that squad.
“If you don’t think that then what’s the point of being here because you’re just happy to sit on the bench or in the stands.
“All the lads here want to play, of course they do, but the gaffer’s got a tough job of just picking 11 players.
“I don’t want to be here to just play second fiddle or just be happy to be on the bench, that’s never been in my nature and it never will be.
“It’s a short career as it is, you want to play as much as you can, I’ll be working hard in training and when I do get my chance I need to try and take them in games.
“If I keep doing that then hopefully the manager gives me the nod and maybe gives me more of a starting spot.”
One element of Liverpool’s game the Scotland international hopes he can help improve upon is the goals conceded column.
But, like his manager, he insisted defensive matters are a concern for the team as a whole, rather than just the back four and the goalkeeper.
“I do believe as a group we can get better defensively and I can be part of that,” he added.
“As a group we have to work together to get better defensively because, if the midfielders can help us and the strikers can help us, then as a team we’ll improve.
“The threat we’ve got going forward, the counter-attacks are frightening at times.
“So, if we can just shore up at the back and not concede silly goals and not switch off then we’ll be a big force.”
