Premier League chief executive Richard Masters says he needs honesty from the 'big six' who were planning to join the European Super League before trust can be restored between the league and clubs.
Arsenal, Chelsea, Liverpool, Manchester United, Manchester City and Tottenham all withdrew from the project within 48 hours after fans protested.
"The concept was so badly wrong and handled very badly," said Masters.
"You need truth before reconciliation."
Speaking to BBC sports editor Dan Roan, he said: "The clubs involved have acknowledged that and have apologised and we're now in the process of talking to those clubs to establish the facts and establish what happened.
