Liverpool boss Brendan Rodgers is wary of the quality of Norwich City's players.
The Canaries have transformed their season since Liverpool thumped them at Carrow Road earlier this season.
Rodgers said: "Chris Hughton and his staff have done a brilliant job making the team harder to beat - they went on a run of games unbeaten - which was a great feat considering how they started. They've got some outstanding players and they'll hope to replicate the performance they had [at Anfield] last season.
"They've got Grant Holt, who is a fighter up front and has quality; Anthony Pilkington on the side is a threat; Robert Snodgrass is a very good technician; Wes Hoolahan is obviously a threat in behind that - but we're at home and confidence has been high."
