The card resting on the wreath placed on seat number 122 bore a simple message.
"Loved, Adored, Never Forgotten. Thank you. The Manchester United Family." Seat number 122 will never be empty. Sir Bobby Charlton will always be here.
The scale of the tributes, the depth of emotion inside and outside Old Trafford on this European night, was evidence - as if it was needed - that Sir Bobby leaves a legacy to his club, his country and to the game that is unsurpassed in its significance and in its beauty.
It was also a reminder that this great club is not about owners, it is not about a myriad commercial deals, it is not even about the bricks and steel that need replacing here. And it is not about a phoney Champions League anthem, that is for sure.
It is about the players, it is about the fans, it is about their connection. Rarely can a silence - pierced only by the skirl of a lone player's bagpipes reminding everyone of the United anthem that says 'We'll never die' - have spoken louder about the respect commanded by one man.
Impeccably observed by the visiting fans, the Copenhagen supporters unfurled their own banner in honour of Sir Bobby after Erik ten Hag had laid a wreath in the centre circle.
The respect from the opposition here was a cameo representing the worldwide respect for Charlton. From United’s point of view, of course, a perfect centrepiece to the occasion would have been some sort of swashbuckling performance, a display that raised the roof after the reverence.
But the stark truth is that there has been little offered by United this season to suggest a blue-chip production is just around the corner. They can still grind out the odd result - like they did here - but the lack of fluidity in their play is sometimes startling.
If they are to upset City in the Manchester derby this weekend, their levels will have to be a couple of notches higher than they were on this emotional night.
It will be equally emotional on Sunday but all connected with United know these tributes should just be the beginning of what would be the best way to honour the great man.
And that, quite simply, would be to make United great again… on the field. They are a long way from that but at least they know seat number 122, Sir Bobby Charlton, will always be with them. Loved, Adored, Never Forgotten.
