After a comfortable home win over Burnley in the Premier League, the Reds left back feels the team are back on track.
He told the Reds' official website about their chances of beating Bayern away from home: "Yes, of course – we have to [believe in our chances].
"Last season we were good away from home in the Champions League, we caused teams problems and that's what we need to do again.
"It will probably be a different game, they'll need to come out a bit more, their fans will demand they try to create.
"It's all about trying to keep them out first and foremost and then hopefully we can take the chances we get and do enough to get through."
Robertson added that Liverpool are firmly focused on the title race.
"It's another game down, eight to go. It's going to be exciting one way or another.
"I've said in all the interviews I've done, we need to give 100 per cent in every single game and whether it gets us a trophy or it doesn't, we need to deal with that.
"The position we're in now, one point behind with eight games to go, if we perform like that – especially with our attitude – then it'll stand us in good stead.
"We've got some tough games coming up but we look forward to the chase and hopefully we can push them all the way."
