Inter can register a full squad in Europe next season after meeting the long-standing conditions for their release from a Financial Fair Play (FFP) settlement agreement.
The Serie A side "have been considered in compliance" with the demands placed upon them in May 2015, the UEFA Club Financial Control Body (CFCB) investigatory chamber confirmed on Friday.
The agreement was struck after Inter breached FFP regulations and were punished with heavy fines and limited to a squad of 21 players in the Champions League this term, down from the usual 25.
