Leeds fullback Warnock: Henderson will prove value at Liverpool
The former Red has been impressed by the improvement our No.14 has made under Brendan Rodgers this season and is tipping him to continue to develop.
Warnock told LFC TV: "I remember watching when they played at Arsenal and he was the best player on the pitch by a mile - the distance he covered and he seemed to be playing in a more advanced role.
"I've played against him and trained with him and know he's a very good player.
"I think the first year he came was probably a bit daunting for him in realising what Liverpool is all about and things like that, but I think he's acquitted himself well this year and been very good.
"People forget he's still young. He's 22 and still has plenty of time to be a great player for Liverpool."
