Aberdeen progressed to the Europa League’s second qualifying round after winning 2-1 with RoPS Rovaniemi in Finland to progress 4-2 on aggregate.
The Dons went into the tie with a 2-1 advantage with Tommi Jantti’s injury-time goal leaving the Dons with little room for error in the second leg.
The Dons got off to a disastrous start in Derek McInnes’ 300th game in charge when Tarik Kada curled home the opening goal for RoPS inside two minutes.
Lewis Ferguson went close to nodding home an equaliser before the Dons were handed the chance to equalise from the spot when the former Hamilton player was fouled in the penalty area by Mahamadou Sissoko.
Sam Cosgrove calmly slotted home from the spot to put the Dons back in control of the tie.
The lively Ryan Hedges went close from distance after the break before Curtis Main made his competitive debut for the Dons after replacing Cosgrove.
Former Ross County and Caley Thistle goalkeeper tipped a Niall McGinn attempt over the crossbar before Dons goalkeeper Joe Lewis made a fine stop to deny Youness Rahimi as time ticked down.
But Aberdeen ended RoPS’ hopes of forcing extra time when Ferguson netted in injury time. His first effort was saved by Reguero but he had enough composure to hook the rebound into the net and book a second round tie against Chikhura Sachkhere of Georgia next week.
