Graeme Shinnie’s 25-yard strike secured Aberdeen a narrow victory over Apollon Limassol in the first leg of the Europa League third qualifying round tie.
The home side surged to an early lead at Pittodrie when Ryan Christie scored with a header after just four minutes.
The Cypriot side grew in confidence and stature in the second half, though, and equalised through Ribeiro Santana.
Yet indiscipline cost the visitors, with Esteban Sachetti dismissed before Shinnie’s winner.
Apollon head coach Sofronis Avgousti had already been sent to the stand, just after the Cypriot side equalised.
It may have been a rare home European win for the Dons, but given their excellent away form in the Europa League they will be confident of seeing the job through in Larnaca next Thursday night; and they did it without their main hitman.
Only Mark McGhee, John Hewitt and Drew Jarvie have scored more European goals for Aberdeen than Adam Rooney, but he may have to wait until the final qualifying round to add the nine he already has.
