But as the joy of their achievement subsided it emerged that European football's governing body Uefa have given the Anfield side an allocation of just 9,000 tickets for the final.
Their La Liga opponents, who have made three Europa League finals in a row, will get the same number for the 35,000 capacity St Jakob-Park in Basel.
A further 9,000 tickets have already been sold by Uefa to "neutral fans" while the remaining 8,000 seats will go to the "local organising committee, national associations, commercial partners and broadcasters, and to serve the corporate hospitality programme" - as reported by the likes of the Independent.
'It sums Uefa up'
And now Aldridge, who scored 50 goals in just 83 games for his boyhood club between 1987 and 1989, has made his feelings on Uefa perfectly clear in an interview with talkSPORT.
"Unbelievable... amazing," Aldridge told talkSPORT.
"Do you know what, I think it sums Uefa up it really does. They're trying to highlight this competition, and rightly so, on the back of the Champions League by giving you the carrot of the Champions League qualification, which was right to do, and then they go back and they go to a stadium that's got 30-odd (thousand capacity), who made that decision?
"That is pathetic... I don't know, I just don't know (but) is it a football person that done it? I don't think it can be."
Uefa are limited by the relatively small capacity of the stadium in Switzerland, but Liverpool fans will still feel aggrieved given the plethora of massive grounds available to them across the continent.
Earlier this week Klopp said as many as 100,000 Liverpool fans should travel to Switzerland for the final.
But the German later begged supporters to ignore his invitation admitting he was "not too smart" to have "spoken like a fan" - as reported by the likes of the Metro.
