Berti did play the whole 120 minutes of that cursed final. Anyway, I really don't see who this mysterious player could be at this point. But perhaps you were thinking of Baresi. Kaiser Franz did get injured in the first game of the tournament, only to make a miraculous comeback just in time for the final, where he played a superb game (the Gazzetta gave him 8,5 the next day as I recall), but missed that fateful penalty in the shootouts lottery. The image of the legendary 34 year old warrior crying on the shoulder of a staff member will remain forever imprinted on my memory.
