Robbie McDaid’s goal late in the first half gave Glentoran victory over HB Torshavn in Thursday’s Europa League preliminary round match in Belfast.
The Irish Cup holders will now be away to Scottish Premiership team Motherwell in the first qualifying round on 27 August.
After a dull opening 41 minutes, McDaid netted a superb first-time right-foot finish to make the breakthrough.
Debutant keeper Dayle Coleing made two good saves to keep Glentoran in front.
The slender victory was Belfast club Glentoran’s first success in Europe since 2011.
Torshavn came into the match five points clear at the top of their domestic league, after 15 wins from 17 matches.
There were few chances before McDaid’s quality strike in the 42nd minute which was set up by Rory Donnelly’s perfectly-weighted pass.
Gibraltar international keeper Coleing made a fine save from Adrian Justinussen’s 25-yard free-kick, while Burundi midfielder Gael Bigirmana made a vital clearance off the line to deny Hilmar Leon Jakobsen.
“We knew this was going to be a hell of a battle, and it was,” said Glentoran manager Mick McDermott.
“The goal was a great finish and came from a great pass by Rory Donnelly.
“Robbie keeps popping up at big moments with big goals.
