Gerrard says the Belgian has the ability to lift the crowd as well as ridicule his opponents.
“He's a unique midfielder because normally midfielders they try and combine around you with a one-two and then they'll run," the Liverpool legend said on BT Sport.
“But he can embarrass you by skill and no footballer likes that whether you're a defender or a midfielder.
“There's nothing worse than a powerful runner running past you with the ball and doing you with skill.
“The crowd lifts from it and you can be embarrassed."
