Second half screamers from Joely Andrews and Chloe McCarron gave an unchanged team an outstanding win over Romanian champions Olimpia Cluj in their Champions League group third and fourth place playoff in Finland this afternoon.
Glentoran dominated the first half but couldn't find a breakthrough. Kerry Beattie and Casey Howe linked up well inside 10 minutes, with the latter spinning away from her marker on the edge of the area before firing over the crossbar.
Howe was involved again when her cross was inches away from meeting the onrushing Nadene Caldwell in the area, and Lauren Wade's shot was narrowly wide as Glentoran continued to press.
A well-worked corner saw Howe threaten again, with Cluj goalkeeper Erin Louise Seppi diving across goal to keep her effort out, and Wade burst into the area but her cut back drifted in behind Beattie and Howe.
Joely Andrews smashed an effort off the crossbar after stealing the ball off the Cluj defence and when Caldwell won a free-kick from the rebound, Wade's strike narrowly dipped over the top.
Glentoran almost made the perfect start to the second half when Andrews slipped in Beattie but her poked effort was well kept out by Seppi, who was again called into action when captain Jess Foy tested the stopper.
However the Glens got the goal they had been craving when a curling cross from Northern Ireland international Andrews evaded everyone in the box and looped into the far corner.
Cluj, who have won the last 10 league titles in Romania, rarely threatened and Mara Batea's strike was comfortable for Ashleigh McKinnon, and Wade almost capitalised on a poor clearance by Seppi but the Romanian goalkeeper recovered well to save.
Wade, Caldwell and Andrews all fired off target as the Glens aimed for a killer goal, which arrived on 85 minutes when NI midfielder McCarron curled home a superb first-time effort into the far corner from the edge of the area.
Rogan's acrobatic effort almost added some gloss but Billy Clarke's side saw the game out to take their first win in the Champions League since 2016.
