Republic of Ireland 0-2 Norway
The Republic of Ireland's hopes of qualifying for next year's Women's World Cup in France are now out of their hands after they were outclassed by top seeds Norway at Tallaght Stadium.
The Girls in Green fell to their second successive home defeat in qualification, having lost by the same margin to the Netherlands in April.
Rosengard striker Lisa-Marie Utland did the damage with a goal in each half, but the margin could have been considerably higher without the heroics of Ireland goalkeeper Marie Hourihan.
Ireland manager Colin Bell went into the game without Manchester City's Megan Campbell, Sunderland's Steph Roche and player of the year Harriet Scott.
And his job was made considerably harder when Arsenal defender Louise Quinn went off with a suspected broken nose ten minutes before half time.
Norway had already taken the lead at that stage, as Utland found space in the box to power home a close-range header from Guro Reiten's left-wing cross.

They had already had a couple of let-offs after Carolie Graham-Hansen hit the side-netting, while Ingrid Syrstad Engen had forced a save from Hourihan.
The Norwegians came agonisingly close to doubling their advantage on the half-hour as Reiten was teed up on the edge of the box, but Hourihan did brilliantly to tip her rasping drive onto the bar.
Isabell Herlovsen should have added to Norway's lead right on half-time but she couldn't find the target with a free header.
Ireland upped the tempo after the break and a stunning run from Leanne Kiernan, after Katie McCabe had set off a counter, came up just short as she couldn't get power behind her shot.
Diane Caldwell's floated free kick caused panic in the Norway defence but no Irish player was on hand to profit from the loose ball.
And disaster struck just past the hour when a free-kick from Graham-Hansen was nodded across the six-yard box and Utland reacted first to smash home her second.

Frida Maanum and Herlovsen forced saves as Ireland took risks in the final stages, while Caldwell's tackle on Reiten was enough to divert the ball onto the post.
That kept the scoreline respectable from an Irish point of view in a game they rarely looked like taking anything from.
The sides meet again on Tuesday in Stavanger, where Ireland will need a win at the minimum and hope the Netherlands take three points when they face Norway in September.
