AEK comfortably held Austria to a 0-0 draw in Vienna to qualify to the knock-out stage of the Europa Cup.
AEK clinched the second place in its group behind AC Milan with five draws and one win.
It will be the only Greek team to continue in Europe after Christmas. On Monday it will be in the draw of the first knock-out stage among the unseeded teams.
The Athens team had the best chance of the game in the first half when Araujo missed the target from a close range with only the keeper to beat.
Austria piled on the pressure in the second half knowing that a goal could have put them through to the next round. However, they rarely threatened AEK’s goal.
