Liverpool must be more creative to beat Plymouth Argyle in their FA Cup third-round replay following a scoreless draw at Anfield, reckons keeper Loris Karius.

Karius told the club website: "We didn't create that many chances - we weren't that creative in and around the box. That's something we can improve for the next game.

"They defended really well, of course. We didn't have that many different ideas to get through their defence, but what they did they were doing well.

"I didn't see them as much in my half - they focused on defending and dealt [with us] really well. They will hope for a crazy game at their ground but we have to be there from the first minute and play our game to go to the next round.

"It depends on us. They will try to stay compact and get one or two counter-attacks. We just need to get some goals. We have to go through clearly - that's our aim."
