what is the point of the confederations cup
FIFA Confederations Cup The FIFA Confederations Cup is an international association football tournament for national teams, currently held every four years by FIFA. It is contested by the holders of each of the six (UEFA, CONMEBOL, CONCACAF, CAF, AFC, OFC) continental championships, along with the current FIFA World Cup holder and the host nation, to bring the number of teams up to eight. The tournament is also described as the Cup of Champions because it is contested by the Champions of each confederation and the world champions with the host.

2018 FIFA World Cup Competing countries were divided into eight groups of four teams (groups A to H). Teams in each group played one another in a round-robin basis, with the top two teams of each group advancing to the knockout stage. Ten European teams and four South American teams progressed to the knockout stage, together with Japan and Mexico.
