The performance of Poland in the U-21 Euro is used to decide if Poland can qualify for the Summer Olympics. Since the team's foundation, Poland only managed to qualify once, the 1992 Summer Olympics thanked for having the best coefficence point among losing quarter-finalists in the 1992 UEFA European Under-21 Championship, but managed to finish second in the tournament.
