Royal Antwerp won a first Champions League game on Wednesday with a surprise 3-2 home victory over Barcelona, securing their first points in Group H although it was not enough for them continue in this season's European club competition.
Barça's loss in Belgium was a surprise but they still finished top of their Champions League group.
But straight from the kick-off Antwerp surged downfield and won the game through another teenage substitute, George Ilenikhena.
It meant Antwerp avoided losing all six of their group games in their Champions League debut but they still finished bottom of the standings.
The Spanish club, who rested regulars, had already secured a top-two place before Wednesday's game and the 5-3 win for Porto over Shakhtar Donetsk in the other group game confirmed Barcelona as group winners despite their defeat.
