City are leading the way in the Premier League, holding a 16-point lead and needing just a single win to be crowned champions.
However, Liverpool are the only team to have inflicted defeat on Pep Guardiola's side in the league this season, with Robertson insisting that 'The Reds' can't be afraid of their illustrious opponents when they play the first leg on Wednesday night.
"I don't think we can be afraid. They won't be afraid of us and we won't be afraid of them," he explained.
"They've been the best team in our league this season and are going to win the league, undoubtedly, but this is two games in the Champions League, a one-off.
"We have as much right to be in the quarter-finals as they do and there is no seeding in it. It will be a big occasion.
"Their movement is a joy to watch at times, and as a defender you need to be aware of that, but hopefully we'll be attacking as well and we can push them back into areas where they don't want to go."
