Agger admits he's improved working with the club captain.
"We all have a different approach to things, but Gerrard is a great football player, a great leader and a great person. So there is a lot to learn from a man like him. Both on the field, but also outside," Agger told BT.
"It's not something I go and think about every day, but to be captain of Liverpool, it will not get much bigger."
