Aluko scored his wonder goal in front of Birmingham boss Alex McLeish, who was at Pittodrie to commemorate when the Dons beat Bayern 3-2 nearly 25 years ago en route to their European Cup-Winners' Cup success over Real Madrid in Gothenburg.
The teenager actually bumped into the former Scotland and Rangers boss in the corridor where he was told to keep up the good work.
Aluko said: "I just met him there and he said, 'Well played'. He said, 'Keep doing that - it's a good experience for you'.
"I will keep learning. I'm here until the end of the season. I just want to keep playing well for Aberdeen.
"When I go back we will see what happens. If I break into the team so be it but I want to keep playing well here and hopefully that will help my career."
