Liverpool boss Brendan Rodgers says he will rotate his squad against Bolton Wanderers.
The Reds are unbeaten in their last nine matches in all competitions but will on Saturday play the first of eight games in a little more than a month and the Northern Irishman admits that rotation is a must.
"We'll make some changes, but it's a game we want to win and we want to progress into the next round," Rodgers told reporters during Thursday's press conference.
"I'll do what I've done right the way through the season and look at our squad. We've got some very good players and we'll look to make changes, but not too many.
"It's always a balance between consistency and rotation, but it's something we're comfortable with. We'll make changes this weekend, but it shouldn't disrupt the flow of our play."
Asked to give a complete update on injured players, the 41-year-old said: "Joe Allen has been back and trained this week, which has been great.
"Glen Johnson has had a good week's training, so he'll be available. Mario [Balotelli] has trained as well, so he is available.
"We're still waiting [on Daniel Sturridge]. He's still working, but he won't be available for the weekend.
"Brad [Jones] is still out and won't be available and Jon [Flanagan] is not part of the squad as of yet."
