GLASGOW (Reuters) - These are heady days for Celtic supporters but even in the euphoria of an unbeaten season the club's past is being remembered with rare pride.

Celtic have just finished their Scottish Premiership season unbeaten throughout the campaign. A sixth straight league title is in the bag and on Saturday, they could complete the domestic treble with a Scottish Cup final win over Aberdeen.
