Former Celtic keeper Packie Bonner believes Aberdeen have every right to feel aggrieved over the award of Jota's winner during the 3-2 thriller at Pittodrie.
Ange Postecoglou 's side were were 2-0 up and cruising but they needed a second goal on the night from their Portuguese star after a spirited fightback from the hosts.
But the decision to allow Jota 's strike incensed Aberdeen's players, coaching staff and supporters who were convinced Liel Abada was offside and then interfered with play.
