Twelve elite clubs announced on Sunday their plans to launch a tournament to rival the Champions League in which they would be assured of qualification.
Real Madrid, Barcelona and Manchester United, among others, would compete in the Super League every season without risk of demotion.
The news has prompted a strong reaction throughout the football world, with governing bodies, rivals clubs, players, coaches and fans critical of the idea and its anti-competitive format.
"At FIFA, we can only strongly disapprove the creation of the Super League, which is a closed shop, which is a breakaway from the current institutions, from the leagues, from the associations, from UEFA, and from FIFA," Infantino said.
