Donovan Moss was the architect of both of Berg’s goals, the left back muscling his way past the opposing defence to cut the ball back to his team mate, who controlled the ball with his first touch and poked his second beyond goalkeeper Zuriel Abejo.

Five minutes into the second half Moss was unlocking the Northern Mariana defence again, this time with a pinpoint delivery from deep. Berg read the flight of the ball perfectly and rose above the defence to steer his header home.

Guam added their third in the 82nd minute when Luciano Jameson launched his cross into the penalty area from the right side and just inside the Northern Mariana half, with Rivera arriving to nod past Abejo with a decisive header.

The win moves Guam onto three points and level with table-toppers Mongolia, who won 7-0 in their opener against Northern Mariana Islands. Mongolia and Guam face off on Sunday.
