The Candystripes coach has praised the Brandywell faithful for their part in the club's progression and said that the FAI Cup success is a proud moment
The Candystripes triumphed 3-2 over St Patrick's Athletic in the final of the competition which took place on Sunday November 4 and Devine was keen to praise the fans for their support.
Speaking to reporters during the club's homecoming on Monday evening, Devine said that it was a 'fantastic' experience to be greeted by thousands of fans.
"It's their club. It's not Declan Devine's or (club chairman) Phillip O'Doherty's, or (team captain), Kevin Deery's. It's the people of this city's club and we will do everything in our power to make sure it stays that way," he told the BBC.
"It is absolutely one of the proudest moments of my life, to walk into a packed Guildhall Square," added Devine. "I have been here many times in the past to see huge events in the Derry calendar.
"And to come here with a bunch of local lads who have been very successful in a major cup competition in Dublin is fantastic," said Devine.
