Jamie Carragher left his CBS Sports colleagues astonished with his recall of granular details from the 1991 European Cup.
The former Liverpool defender discussed Red Star Belgrade's run to lifting the trophy against Marseille on penalties.
That was five years before Carragher had even started his professional football career, showing his devotion to learning about the game.
Carragher was able to recall Red Star's penalty shootout win, change of tactics, and their run to the final, though it is likely he would have done some research before discussing them on CBS, as last night they played RB Leipzig and lost 2-1.
