Khalid Sinouh who turned out in goal for the Sky Blues in their final pre-season game at Port Vale last Friday has been released by the club.
Micky Adams has said that he is looking elsewhere for a keeper but apologised to the former RKC Waalwijk custodian at half-time during the friendly.
"You don't know about trialists until you throw them into the thick of the action," said Adams to the CET. "It was very difficult for him and I apologised to him at half-time. "With the back four in front of him,it would have been a difficult ask for any goalkeeper."
