Nyon: UEFA appointed in-house investigators Wednesday for disciplinary cases against European Super League organizers Real Madrid, Juventus and Barcelona.
The three clubs could be banned from future Champions League or Europa League competitions and fined for refusing to renounce the project which collapsed within 48 hours of being announced last month.
The nine other rebel clubs reached settlements last week to commit to UEFA competitions and pay millions of euros (dollars) in forfeits of future prize money and donations to a UEFA-run charity.

The focus for inspectors will be a potential violation of UEFA's legal framework in connection with the so-called Super League' project, UEFA said.
The European soccer body's legal statutes include a section that prohibited groupings of clubs or leagues forming without UEFA's permission or outside its control.
No timetable was given for the UEFA investigation.
Disciplinary charges typically follow at least three weeks after investigators are appointed.
Any UEFA sanctions could be challenged at the Court of Arbitration for Sport.
