Manchester City striker Erling Haaland admits he doesn't know how to take a throw-in.
Haaland says he's unsure of the rules.
He explained: "But what annoys me is throw-ins.
"If you throw this way or that way, it doesn't matter. Just make sure you have two hands on the ball.
"I don't even know the rules, and if I'm going to make a throw, I'll probably do it wrong.
"But it doesn't matter if you throw the ball straight down, straight up or whatever. I would change that.
"And you can't steal too many meters, there should be a limit to how far you can go and a limit to how long you can take.
"I think it will be like that in the future."
