Brendan Rodgers's men currently occupy fourth spot in the Premier League, with a six-point cushion over nearest challengers Tottenham on their way to what would be their first progression to Europe's top competition since 2008-09.
The defender is confident of the Reds' chances but says they must remain level-headed to be certain of reaching their target.
"Southampton [on Saturday] is a tough place to go but I think we can score goals and defend well as a team and we are working hard. We are in a good position at the moment [but], with 11 games to go, there are still a lot of things that can happen. We need to stay calm and focus on the next game.
Toure highlighted the motivational role played by Rodgers, enthusing: "The gaffer gives everyone confidence. When you step on the pitch you know that he's behind supporting you.
"Everyone is trying to do their job the best they can and we need to keep doing that until the end of the season."
