The three clubs were threatened with severe punishment for their refusal to drop out of a plot to create a new competition
Barcelona, Juventus and Real Madrid will not face further punishment from UEFA for their role in founding the Super League.
The three clubs are the only founding members of the breakaway competition that have so far refused to abandon the project.
UEFA threatened the Spanish and Italian sides with legal action and it was reported they could be suspended from the Champions League, but it was announced in May that proceedings would be delayed after a Madrid court accused the governing body of acting "outside the rule of law".
