Liverpool midfielder Adam Lallana says they've struggled without the injured Daniel Sturridge.
Sturridge aims to be back for their clash with Crystal Palace.
Lallana said: "After losing Luis Suarez and missing Daniel Sturridge up top lately, it's been difficult.
"But we've had to find different ways of winning games; other people have had to chip in with goals.
"It was great for Mario Balotelli to get a goal against Swansea in the League Cup and now we are through to the quarters.
"We know we've not been playing to our maximum but we are still in transition. We feel that if we keep working hard, a really good performance is around the corner."
