"The role our crowd can play is massive and they give us such a big belief in ourselves," said the midfielder.
"Playing at Anfield on a European night is always a special occasion and the crowd give us a real boost and the energy that we need for winning the game.
"This is such a massive match. We are 100 per cent focused and have confidence. We made some mistakes in the first game at Stamford Bridge and we were really disappointed with the way we played because we didn't do enough going forward.
"We know we have to do better going forward this time and we have to score a goal. It's important not to concede a goal but we have a lot of belief we can score two goals. We beat them in the Premiership 2-0 at Anfield this season, when we scored two goals in the first half and we played very well in that game."
