AC Milan and Juventus have not yet withdrawn from the breakaway competition and could lose their place in the Italian top-flight
Italian teams who agree to join unauthorised competitions such as the Super League will be banned from competing in Serie A, Italian football federation (FIGC) chief Gabriele Gravina has warned.
Juventus, Inter and AC Milan were among the founding members of the competition which was announced over a week ago.
The plot to create the Super League to compete with the Champions League fell apart rapidly, as several teams reversed their decision to join following threats from football associations and protests from fans.
