The defender was cut from the squad after being quizzed by police for his involvement in Scommessopoli, but states the Azzurri coach promised him a place in the event of emergency
The Zenit St Petersburg full-back was dropped from Prandelli's provisional selection after being implicated in the Scommessopoli scandal, but he insists he was instructed to remain on standby in the event of an emergency.
"When my exclusion [from the Italy team] was announced, the coach said, in the presence of [FIGC vice-president Demetrio] Albertini, that if there was an injury someone would call me," Criscito told reporters.
"I'm so sorry for Andrea. I support all my friends and I hope and believe that he can still participate in the European Championship.
"However I will continue to ensure that I am ready [for a recall]."
But despite his pleas to return to the side, Italy have instead notified Cagliari defender Davide Astori to return from his holiday in Miami after he was originally cut from the initial 32-man preliminary squad.
The Azzurri's first game of Euro 2012 is against reigning champions Spain on June 10.
