Jordan Henderson and Dejan Lovren come into the starting XI at Anfield, replacing James Milner and Joel Matip from the side that defeated West Ham United.
"[It's] to keep them all going. They are all in good shape," said the manager.
"Millie got a knock in the last game; he is in really good shape so we thought long about what he could do.
"But we have 11 100 per cent fit players so we should not risk anything. That's the reason."
