The 35-year-old, who most recently played for the Clarets prior to his ban for breaching betting rules, is to take charge of the League One side from the summer on a deal that runs through until 2021.
Barton has been involved in a number of distasteful incidents both on and off the field during his career, but Dyche insists that the unexpected appointment could yet pay off.
"I don't think it's such a surprise to me, he has a thirst to coach and manage," he told reporters. "He's a strong professional, Joey. He was first-class [at Burnley] and there is a student of the game in him.
"He wants to learn and progress. He's got an opinion for sure, a strong opinion, but he doesn't think he's got every answer and he's willing to listen and take advice.
"Fleetwood are a very good club but you could argue he could have waited and tried to get in at a higher level. But he's accepted the challenge and he's willing to get his hands dirty. I've played in those divisions and it's not easy."
