Lucas remains positive

The Reds need to score at least three times at Stamford Bridge after losing the home leg 3-1. It's a difficult task but not an impossible one, especially for a team that has won 4-1 at Old Trafford this season insists Lucas.

"We know it will be really difficult but it's not impossible. Chelsea came here and scored three, and we have the quality to do the same there," said the midfielder.

"We will have to try until the very last minute at Stamford Bridge. I think we need the perfect performance.

"It's a different game but we have shown already this season we can win 4-1 at places like Old Trafford."
