A match between the champions of two confederations sounds like a clean comparison. The calendar makes it something else, because the two clubs almost never arrive in the same competitive condition.
The hemispheres run different seasons
European club football runs from late summer to late spring. Several South American and Asian competitions follow calendars aligned to their own climates and domestic structures.
Any fixture between them lands mid-season for one side and near the start or end for the other. Preparation, sharpness and squad stability differ accordingly.
There is no scheduling fix, because moving the date only reverses which club is inconvenienced. The mismatch is structural rather than a planning failure.
Squad continuity is broken by transfer windows
Champions are crowned at one moment and play the intercontinental fixture at another, with a transfer window often falling in between.
A club can therefore arrive without several players who won the title that qualified it. The team on the field is a successor to the champion rather than the champion.
This affects some confederations more than others, because clubs that sell players into wealthier leagues are the ones most likely to be rebuilt between qualification and the fixture.
Travel and altitude are not symmetrical
Long-haul travel before a single decisive match is a physiological handicap, and the burden falls on whichever club is furthest from the venue.
Neutral hosting was intended to equalize this. In practice a neutral site can be far from both clubs, converting an advantage into two disadvantages.
Altitude and heat add another layer, since a venue chosen for commercial reasons may resemble neither participant's home conditions.
The competitions themselves are not comparable
Winning a continental title means different things in different confederations, because the number of rounds, the strength of the field and the travel involved all vary.
A champion emerging from a compact, wealthy field has faced a different test from one that won a tournament spanning several thousand miles of qualifying.
Treating the resulting match as a ranking of continents therefore overstates what it can measure, whatever the result says.
Expansion changes the question rather than answering it
Larger intercontinental formats with more teams and more rounds reduce the influence of a single match, which is a genuine improvement in what the competition can establish.
They also consume more dates in a calendar already contested by domestic leagues, continental competitions and international windows.
The trade is more evidence in exchange for more fixtures, and clubs have taken positions on it based mostly on whether they expect to qualify.
