Cagliari president Massimo Cellino has offered to resign.

The board have voted to reject his resignation and it is believed that a final decision on Cellino's future in the role will only be taken in the summer.

"It was my duty to resign because I was struck by a criminal investigation and did not want to involve the board of directors against their will," Cellino explained to L'Unione Sarda.

"In March, they will meet again to decide the future of Cagliari.

"Although I think this [investigation] is science fiction fantasy, if called to trial, I will resign immediately and irrevocably, I am not attached to a role like some of the directors."
