Celtic's win against AC Milan should stand alongside any of the great Parkhead nights - and yet the headlines will say something different.
And that is a real sadness as Gordon Strachan's side added another chapter to the recent Scottish success stories of the national team's win in France and Rangers' victory away to Lyon.
The debate will surround the brainless invasion by a single fan who reached out to AC Milan keeper Dida after Scott McDonald's last-minute winner.
First things first. No-one can or should condone any fan entering the field of play, even if it was all in a moment of ecstasy as Celtic stunned the Champions League holders.
Celtic must be punished and the fan involved must be banned from Parkhead.
But let's calm the talk of games being played behind closed doors or points being taken from Celtic.
And this is because we have to question the reaction of Dida to what was a stupid, but not dangerous, tap on the neck by an over-exuberant idiot.
The clues are in the pictures.
Dida was touched on the neck, and even set off in pursuit of the supporter for several yards before a light went on and he crumbled to the floor clutching the side of his head.
No excuses for the fan, but what followed was farcical, with ice packs being applied and Dida stretchered off - and stretching the point.
If this was the sort of physical contact that removes Dida from the field of combat, he will be safer staying at home in future, but well away from the feather-duster.
This was not an assault. Dida was not punched, although those who say the fan could have been carrying a weapon have a valid argument.
Referee Markus Merk reviewed the incident and refused to comment and Uefa has followed suit.
When they do, it is to be hoped that Celtic suffer a hefty fine for allowing the fan to invade the pitch, but surely there can be no more punishment.
Dida's reaction looked like opportunism in the extreme, and he should reflect on his behaviour with a level of embarrassment only just below that of the supporter who brushed against him.
In fact, while Uefa is studying the behaviour of Celtic's fan, they should also question whether Dida's own reaction also damaged the spirit of the game.
Celtic's win did their manager and players huge credit, backed once more by a fanbase that makes them almost invincible at Parkhead in Europe.
To allow one fool to spoil the whole party would be desperately sad.
AC Milan also have a genuine right to feel aggrieved at the lack of security that allowed the fan to enter the field of play.
But anything other than a Uefa fine for Celtic and a lengthy ban for the supporter would not be in keeping with the severity of the incident.
Common sense must prevail.
