Football will resume in the English top-flight from June 17.
The Reds need just two wins from their last nine games, but Robertson says the players aren't getting ahead of themselves.
He told the club's website: "The light at the end of the tunnel was just getting back into training, to be honest. At times, there were some days you didn't think that would have been possible, but now we're back here, we can look forward and look to the next step.
"Then, like I said, hopefully with the games we've got ahead of us, we can get back to it. Would we like to play in front of 55,000 people at Anfield? Of course we would. Winning games or whatever without the fans won't feel the same, but it's something we know we need to go through and it's something we know that in their houses and stuff they will be supporting us like mad and we'll feel that support.
"Hopefully we can celebrate a title if we get the job done – and there will be time to celebrate it when the time is right. But for now we need to keep focused, we know whatever games are coming up and whenever they start, we need to get them won and get that trophy for this club."
