Second half goals from Bastien Hery and new signing Christy Manzinga helped Linfield to victory over Tre Fiori in their UEFA Champions League Preliminary Round semi-final in Nyon, Switzerland.
The French duo struck to ensure the Blues booked a place in Tuesday's final against either Drita or Inter Club d'Escaldes with a Qualifying Round place awaiting the victors.
Linfield enjoyed the majority of possession in a first half of few opportunities with perhaps the best chances coming around the ten minute mark when Shayne Lavery's effort from a Niall Quinn through ball was blocked.
Kirk Millar was twice denied by the Tre Fiori keeper early in the second half as David Healy's side stepped up a gear.
But the deadlock was eventually broken on 71 minutes when Hery unleashed a great right foot strike into the top corner to give keeper Aldo Simoncini no chance.
Then, with seven minutes remaining, Manzinga made sure of Linfield's progression with a tap in after Simoncini misjudged a Chris Johns punt forward.
Tre Fiori were reduced to ten men late in the game when Giacomo Procacci was dismissed by Hungarian referee Balazs Berke for a challenge on Millar.
