It was a fifth Premier League defeat already of the season for the Reds, but Robertson says no-one inside the dressing room is giving up on the title.
"Obviously, we've given ourselves a huge uphill battle, but I don't think any of the teams will really look at the league table until we're halfway through," vice-captain Robertson said post-match of Liverpool's position.
"That's what we've got to do but we've got to pick up points on a more consistent basis. Then let's see where we are after Christmas time or whatever. We've just got to focus on ourselves and focus on performance levels.
"I don't think you can talk about the title this early on in the season, regardless of what position you're in, but you need to then consistently start winning games again for that to even come into question. It's definitely not a question that's getting spoken about in the changing room or anything."
