Not sure about Aberdeen V Maribor, I noticed Ibraimi their playmaker who was their best player when they played Celtic last season signed for Astana who Celtic are to play so they might have lost some of their other best players too. They were quite lucky to knock us out too when they did I always thought we were comfortable against them, im sure Johansen blocked a Van Dijk header on the line that would have put us 2-0 up away from home.
They're a decent team but I think Aberdeen could beat them.
Although they have a good few scalps in Europe in recent years, have beaten Celtic, Rangers, Palermo, Wigan, Zulte Waregem and Panathinaikos and have drawn with Chelsea, Tottenham, Sevilla, Celtic, Rangers, Sporting Lisbon, Schalke and Braga. Results that would be beyond Aberdeen.
