Teams from each of the six international football confederations will be at the Club World Cup: Asia (AFC), Africa (Caf), North and Central America (Concacaf), South America (Conmebol), Oceania (OFC) and Europe (Uefa).

In most cases, winners of the confederations’ equivalent to Uefa’s Champions League over the four seasons from 2020-21 to 2023-24 have qualified.

In the OFC’s case, it is the best-performing winner across the four years.

There are 12 places for European clubs – the most from one confederation. These places are decided by clubs’ Champions League performances over the four-year qualifying period.

That means recent winners Chelsea, Manchester City, Real Madrid and Paris-St Germain have all qualified, though PSG’s qualification was not as a result of winning last month’s Champions League final.

Other European teams have qualified through a Uefa ranking system determined by clubs’ performances over the four qualifying seasons. Only two clubs per country can feature, unless more than that win a confederation’s premier club competition in the qualifying period.

Austrian side Red Bull Salzburg – who will be known as FC Salzburg because of Fifa sponsorship regulations – will be present. They have qualified by virtue of being the highest-ranked club across the past four Champions League seasons from a country that does not already have its two spots occupied.

There were four club places each for Asia and Africa, as well as the North and Central American federation, with the United States awarded an extra place as hosts.

Six places are awarded to South American clubs, and one to Oceania.
