The midfielder did not have his contract with the Candystripes renewed and, despite an acrimonious exit, believe he leaves the club with dignity
Deery, who has been troubled with a series of injuries in recent years, ended time at the Brandywell in bitter fashion, taking a swipe at the club's new manager in a message circulated online, where he announced that he had not been offered a new contract with the Candystripes for the 2014 season.
However, the midfielder explained that it was not his intention to offend the Dubliner with his comments.
"I honestly didn't mean to offend him," Deery told the Derry Journal. "He could be the best manager in Ireland for all I know as I’ve never played for him, but that’s how I felt at the time as I believed he was hateful to me in particular, since arriving at the club.
"That’s how I felt and that’s the reason why I posted what I did on Facebook."
A Derry native, Deery highlighted his commitment to his local club through the years and also acknowledged the support given to him by the north-west outfit through difficult times.
"I believe I can walk away from Derry City with my head held high," continued the 29-year-old. "I’ve given the club everything I could give it.
"I’ve never left the club despite the financial difficulties it had faced and I’ve been here for close on 12 years. And the club has also been excellent to me and I would like to thank everyone associated with the club for that.
"I have some fantastic memories and I wish the club all the best. I would never say anything against the club as it has always been good to me."
