The Reds face Zenit St Petersburg on Thursday at Anfield for a place in the last 16 of the competition.
The 28-year-old told the team's website: "We lost 2-0 but you saw the chances we had, six or seven great chances in a European game away is quite good.
"We didn't finish it off and made it hard for ourselves, but with the crowd behind us on a big European night I'm confident with the way we're playing that we'll win the game.
"Scoring goals and putting chances away, that's what wins you games. The goals [against Swansea on Sunday] were great finishes, we have to do that week in, week out, not just now and again."
