Out of concern for the integrity of players, and also because of the lack of financial incentive, several European champions declined to participate; in all cases, their runners-up took their place. The 1975 and 1978 editions were not played at all. The very viability of the competition came under fire until Toyota assumed the role of sponsor for the 1980 edition; for the remainder of the competition's history, no club declined playing the Intercontinental Cup, and the competition always took the form of a single match held on neutral ground, in Toyota's home country Japan. This cup was played for the last time in 2004, being replaced by the FIFA Club World Championship from 2005.
