Premier League clubs are reviewing their multi-million pound relationship with fan tokens firm Socios after an investigation raised serious questions about its business practices.
Arsenal told The Mail on Sunday that they had approached Socios and parent company Chiliz for more details on the allegations around its chief executive Alexandre Dreyfus and the supposed non-payment of staff.
Supporters groups, meanwhile, have said the report highlights how leading sides have been too quick to enter into partnerships with crypto-based companies.
The investigation by the website Off The Pitch found that Dreyfus, a French internet entrepreneur, had advised against paying high-profile individuals to protect the value of his firm’s cryptocurrency.
