Kylian Mbappe has stolen the headlines this week following official confirmation that the Frenchman will move from Paris Saint-Germain to Real Madrid next season.
The blockbuster move has been a long time coming, but only in the aftermath of the Spanish giants clinching their 15th European Cup was the much-anticipated move confirmed.
The 25-year-old forward has, of course, already played against Celtic under the Paradise lights – back in 2017 when PSG, then led by Unai Emery, travelled to Glasgow in Group B of that season's UEFA Champions League.
Brendan Rodgers' side took a bit of a beating that evening, with the French outfit (who'd go on to win Ligue 1, the French Cup, the French League Cup, and the Trophee des Champions) putting five past the hosts without reply.
Mbappe, then aged 18, scored the second goal of the night – and then scored again on home soil, when Emery's outfit overcame the Hoops 7-1 in Paris.
From PSG to Bayern Munich, Atletico Madrid and, indeed, Real Madrid having locked horns with Celtic at Paradise in recent years, we've hardly been shy of glamour ties in Glasgow.
That said, the disparity in transfer budgets and television money elsewhere has meant these high-profile ties come with a degree of inevitably that doesn't exactly fall in Celtic's favour.
Which begs the question: Have we had enough of glamour ties at this point, especially in light of the manager's desire to progress the club in Europe?
Naturally, the seeding of participating teams determines the likelihood of these types of games, but the format's familiar complexion is set to change next season.
Next season's Champions League adopts a new format, meaning teams will play eight matches in a new league phase.
Unlike the former group stage, teams will no longer play three opponents twice home and away, but instead will play eight different teams – half of which will be played at home, the other half away.

Which could see Celtic roughing it out in the lower half of the table against better-matched opposition.
Teams that finish in the top eight of the league phase will progress directly into the last 16, with teams that finish between 9th and 24th entering a play-off round to qualify.
The 12 clubs that finish 25th and below will be eliminated from the competition altogether, and there will be no parachute into the UEFA Europa League.
Brendan Rodgers' return last season is remembered for his ultimately prescient "see you in May" comments, but the manager also stressed a desire to oversee tangible progression in Europe.
Like any other Celtic fan, I love the pre-match Champions League anthem, and I thoroughly enjoy watching the best players from all over the world playing at Celtic Park. But I'd also love to see Celtic make strides in Europe - I'm just unsure what that looks like through the lens of the modern game.
Who knows how we'll fare in the throes of the new Champions League system, glamour ties, Kylian Mbappe or otherwise. In any event, the draw date for the group stage is August 29, 2024.
