Liverpool midfielder Lucas Leiva insists Andy Carroll will prove his worth.
The £35million forward was on the bench for the Reds' triumph at Chelsea.
Lucas said: "Andy has struggled a bit at Liverpool but he has the potential to be a very important player for both club and country.
"With him on the pitch we have to change the style of play a bit, relying more on high balls.
"But he is a crucial player for those games where physicality plays a major part.
