Norway produced an impressive second-half performance to defeat Wales 3-1 in their UEFA Nations League clash at the Ullevaal Stadion in Oslo.
Antonio Nusa, Andreas Schjelderup and Erling Haaland scored for the hosts, while David Brooks found the net for the visitors.
The result was a major setback for visitors, who were unable to avoid relegation from League A after another disappointing performance in the competition.
Norway, meanwhile, kept their hopes of progressing alive with an important three points as they would hope Portugal claim victory against Denmark.
The Norwegians started the match with more possession as Martin Odegaard, Oscar Bobb and Nusa tried to find openings in the Welsh defence.
However, Wales remained organised and looked dangerous whenever they moved forward in search of a goal for themselves.
Haaland struggled to find space against the visiting defenders, while Nusa was unable to make the most of an opportunity in the 29th minute when his effort went over the crossbar.
The host came close again in the 31st minute. Haaland held up the ball outside the penalty area before laying it off to Thelo Aasgaard, whose low shot was deflected wide.
The away side also created several chances. Dan James was particularly dangerous and had three good opportunities during the first half.
His effort from a tight angle in the 43rd minute was saved by Norwegian goalkeeper Egil Selvik. The rebound also failed to fall kindly for Lewis Koumas or Liam Cullen.
James had another opportunity after Harry Wilson played him through, but Norway managed to clear the danger as play carried on.
Despite both teams creating openings, neither side could find the breakthrough before the referee sent them into the dressing rooms at half-time with the score still 0-0.
Norway returned with greater attacking intent and finally broke the deadlock in the 59th minute.
Nusa produced an excellent piece of control to bring down a difficult cross-field pass before driving towards the Welsh defence.
He won a corner, and after Wales failed to clear the resulting delivery properly, the ball fell back to the Norwegian winger.
The 21-year-old moved inside before firing a low shot into the bottom-left corner, leaving goalkeeper Karl Darlow with no chance.
Norway doubled their advantage in the 68th minute through Schjelderup. Odegaard started the move with a pass down the left, and Nusa carried the ball forward before finding Haaland inside the penalty area.
Instead of shooting, Haaland unselfishly passed across goal to Schjelderup, who finished from close range to make it 2-0. Wales refused to give up and found a way back into the contest in the 79th minute.
Harry Wilson provided an excellent pass into the right side of the penalty area for David Brooks. The Welsh forward held off his marker before lifting a clever finish over Selvik and into the net.
The goal made it 2-1 and gave Wales renewed hope of getting something from the match. Norway restored their two-goal advantage in the 88th minute after Wales made a costly defensive mistake.
Ben Davies failed to deal with a ball properly and his header went straight to Erling Haaland.
The Manchester City striker moved the ball forward before passing to Schjelderup, who was brought down from behind by Connor Roberts inside the penalty area.
The referee immediately pointed to the spot and booked Roberts for the foul. Haaland stepped up and confidently sent Darlow the wrong way, placing his penalty into the bottom-right corner to make it 3-1.
The goal was another important milestone for the Norwegian striker, who took his international tally to 66 goals in 60 appearances.
Wales continued to search for another goal, but Norway defended their advantage. Harry Wilson was booked for encroachment and arguing during the penalty incident.
There were further opportunities in stoppage time. Haaland narrowly missed the target after getting through on goal, although the offside flag was raised.
Nusa then produced another brilliant individual run, beating two defenders before forcing a save from Darlow. Haaland collected the rebound, but Davies made an important block to prevent Norway from scoring a fourth.
The final whistle from the referee confirmed a 3-1 victory for Norway, giving them three valuable points against Wales in the UEFA Nations League Group A4 campaign.
The result dealt a serious blow to Wales, who were confirmed to have finished bottom of the group and suffered relegation to League B.
Norway will now turn their attention to their next meeting with Denmark, while Wales face Portugal in their final group fixture.
Meanwhile, the game between Portugal and Denmark today will do a lot of favor to the Norwegians who might remain second place after this round of games.
