England’s ‘big six’ clubs have already withdrawn from the competition, which was put together by 12 founding members on Sunday to rival the UEFA Champions League.
Only Real Madrid, Barcelona, AC Milan and Juventus remain in the proposed competition, which has drawn widespread criticism from the footballing fraternity.
Inter released a statement which read: "FC Internazionale Milano confirm that the club is no longer part of the Super League project.
"We are always committed to giving fans the best football experience; innovation and inclusion are part of our DNA since our foundation. Our engagement with all stakeholders to improve the football industry will never change.
"Inter believes that football, like every sector of activity, must have an interest in constantly improving its competitions, to keep on exciting fans of all ages around the world, within a framework of financial sustainability.
"With this vision we look forward to carrying on working together with institutions and all stakeholders for the future of the sport we all love."
La Liga leaders Atletico Madrid, released a statement of their own which read: "The Atletico de Madrid board of directors, meeting this Wednesday morning, has decided to formally communicate to the Super League and the rest of the founding clubs its decision not to finally formalise its adherence to the project.
"Atletico de Madrid made the decision last Monday to join this project in response to circumstances that no longer exist today.
"For the club, harmony is essential between all the groups that make up the rojiblanca family, especially our fans.
"The first team squad and their coach have shown their satisfaction with the club's decision, understanding that sporting merits must prevail over any other criteria."
