Gerrard said: "Fernando is getting a lot of praise at the moment and rightly so because the way he has settled into English football has been amazing and the way he has played is frightening.
"It can be difficult for players from abroad to settle into English football but at the moment Fernando looks like he's been playing here for years.
"Everyone is talking about the goals he has scored and the way he has scored them but we should not lose sight of all the hard work he is putting in off the ball.
"He defends from the front and doesn't allow defenders to have a second on the ball. If they even think of dwelling on it, he is on to them straight away.
"He is always looking to help the midfielders and the defenders and that makes a big difference. I'm made up to have him in our team."
