Admittedly it isn’t a sporting trilogy as celebrated as the Ali-Frazier duels, but for pure sporting theatre, the Scottish League Cup finals contested between Rangers and Aberdeen at the end of the 1980s deserve a great deal of respect.
Anything that you may want from a cup final was crammed into the three clashes between 1987-89. Late goals, agonising misses, extra-time, penalty despair, goalkeeping heroics. Perhaps the only thing missing was a red card or two, which was a little surprising given the growing animosity between the clubs.
