Aberdeen capped a memorable week for Scottish clubs in Europe by defeating Dnipro in the Uefa Cup on away goals.
Darren Mackie scored a priceless away goal for the Dons
The Dons progressed to the group stages courtesy of Darren Mackie's superb header after 27 minutes.
Richard Foster sped away from his marker and his cross was headed home by Mackie from inside the six-yard box.
Andriy Vorobey scored a lucky equaliser when he deflected Andrew Considine's clearance into the net, but Aberdeen held on at the Meteor Stadium.
Aberdeen boss Jimmy Calderwood handed Mackie his first start since August for the crucial UEFA Cup first-round second leg in Ukraine.
Mackie, who recovered from a niggling hamstring problem, replaced Lee Miller up front as the Dons looked to his pace to get them an away goal following the goalless first leg at Pittodrie.
Left-back Foster also came in, with Jeffrey de Visscher dropping to the bench.
Aberdeen goalkeeper Jamie Langfield prevented the Dons from conceding within the opening five minutes when he saved superbly from Lyopa.
Jamie Smith was sent clear on the left-hand side after a brilliant pass from captain Scott Severin, but his tame effort was deflected clear for a corner and the Dons failed to capitalise.
Aberdeen settled into the game well in the opening 20 minutes and appeared content to concede midfield possession and try to hit Dnipro on the break by utilising Mackie's pace.
The tactic worked to perfection after 27 minutes when the SPL side stunned the hosts by scoring a priceless away goal.
Foster sent in a juicy cross from the left wing after evading his marker and Mackie was on hand to head powerfully past Dnipro goalkeeper Vyacheslav Kernozenko for his 50th goal for the club.
Aberdeen continued to frustrate their hosts with some dogged defending, when Lyopa did burst into the area Michael Hart produced a perfectly-timed sliding challenge that triggered unsuccesful penalty claims.
Jamie Langfield was in superb form in Ukraine
Hart then repelled Vitaliy Denisov's low cross and Nazarenko's long-range effort following the resulting corner was blocked.
Lyopa and Vorobey were trying to give Dnipro width, but Aberdeen remained resolute and retained their lead at half-time.
Smith was withdrawn at half-time with a troublesome calf injury and was replaced by Miller.
Aberdeen were camped in their own half from the start of the second period, but were looking comfortable - despite Dnipro pressing for an equaliser.
Langfield was confident dealing with numerous cross-balls and some of the Dnipro players were too quick to tumble under Aberdeen challenges in an attempt to get free-kicks.
Dnipro almost equalised after 62 minutes when Rusol's header from a corner cannoned back off the crossbar.
Zander Diamond went close with a header with 20 minutes remaining as the Dons looked to score a second to seal victory.
Dnipro drew level in bizarre circumstances after 75 minutes when Considine's attempted clearance was deflected in by Vorobey to set up a tense finish.
Langfield was inspirational as he tipped a late shot onto the crossbar and the Dons held on to progress to the group stages of the Uefa Cup.
