Mohamed Elyounoussi gave Norway the lead in the second minute but, afterPaddy McNairequalised, Haaland got the goal of the game with an emphatic half-volley from the edge of the box that had keeperBailey Peacock-Farrellrooted to the spot.
Alexander Sorloth made it 3-1 when he scored from a cross at the far post and the striker doubled his tally two minutes after the restart when Norway launched a counter-attack and Haaland forced his way through to lay it on a plate for a simple tap-in.
Haaland then got his second by completing a fine move in which the ball moved up the pitch with precise one-touch passes for the 20-year-old hitman to curl it into the top corner.
