What the match is
Two champions, one neutral city
Unlike the domestic super cups, this one never has a home side: UEFA stages it in a different city each year, the way it stages its finals. That shapes the audience — a large share of tickets go to neutral and local buyers, and the two clubs' travelling supports take the ends.
The pairing guarantees pedigree by definition: whoever lifts the Champions League and Europa League is in it. That also means the match can pair giants — or hand a mid-sized Europa League winner the biggest occasion in its recent history.
