Brewster has impressed in preseason.
“There's not many better strikers in the world to learn from than Bobby and watching him, how he does the defensive job and the runs he makes," says Milner to the Liverpool Echo.
“Rhian is a different player to Bobby but he still has to do the job that Bobby does so well – to set the press off and be in the position to block the number six.
“Rhian's a goalscorer, you see the positions he takes up, he just needs minutes, he needs game time and he needs to be training, learning and taking everything in. He listens to the guys around him who are trying to help him."
