Liverpool captain Jordan Henderson admits James Milner will be missed inside the locker room.
Henderson has detailed how Milner set standards within the squad.
He recalled to the Daily Mail: "I remember when he came in, he said he wanted to win the Champions League here.
"He doesn't get the headlines but he is so important to a successful team and everything that goes on in the background that people don't see. He is a world-class footballer. You can talk about him working hard and being a leader but he's top, top level.
"The level of detail he goes to in order to ensure he is properly prepared is ridiculous. Doing the right things, eating the right stuff, creating the team environment, in the gym constantly.
"We've built a relationship up where it is good cop-bad cop. Milly collects the fines and things are very much black and white. The lads say to me, 'Hendo, I got stuck in traffic, it wasn't my fault'. They know I'm softer. Milly? Not a chance. It's just, 'Fine! No! It's done!' That's him."
