Norway head coach Stale Solbakken predicted Haaland would make a "very big impact" at his first major Finals, and the City star was quick to deliver on that promise.

Antonio Nusa's trickery was a problem for Iraq, and his incisive pass released the overlapping David Moller Wolfe clear before Haaland stretched to steer in the low cross from the left.

Iraq, who lost all their of group games on their only previous appearance, did not let that get to them as they equalised 10 minutes later.

Amir Al-Ammari found space just inside the area and clipped in a cross, with Hussein rising brilliantly to power a header past Orjan Nyland.

But Iraq only had themselves to blame as they giftwrapped Haaland's second of the contest.

Goalkeeper Jalal Hassan was slow to react to a softly-hit backpass, his attempted clearance smacking off Haaland's shin and ricocheting into the net.

Ostigard nodded in Odegaard's corner on 76 minutes to seal the points for Norway, before Haaland was thwarted by Hassan when another loose pass sent him clean through and seeking his hat-trick.

Haaland nonetheless had a hand in Norway's late fourth, his looping header back across goal deflecting off Hussein before trickling over the line.
