Haaland had to wait until the age of 25 not just to make his World Cup debut, but his international tournament bow too.
And the Leeds-born striker is clearly eager to make up for lost time.
“He’s the opposite of Mbappe and Messi,” Williams said. “He’ll beat you without the ball, which makes it even more dangerous.
“You want to help your midfield by squeezing up, so they don’t have to cover too much distance.
“But as soon as you leave the space in behind, he’s going to exploit that straight away.”
One of the keys to limiting Haaland’s influence, Williams says, is to prevent his team mates getting the ball to him.
“You’ve got to stop the balls in behind first and foremost,” Williams said. “Stop the supply going into him.
“If you can play your distances between your midfield and limit his chances, you’ve got half a chance.
“There’s not many times when he actually drops in, gets the ball, beats four players, and scores his own goal, so he does feed off what he’s getting served.”
Haaland is the most clinical of the four, with 57 goals in just 51 caps.
“He’s more lethal,” Williams added. “If he gets a chance, it’s probably going to be a goal.”
What about dealing with Haaland one on one?
“Around the box, you’ve got to get tight and try to get him on his right foot,” Williams said.
“Then you’re just going to have to be as strong as you can, don’t be clever, just get the ball away and buy time.”
