Barton played for Dyche at Burnley and the Clarets boss says he saw the signs of a potential manager.
Dyche said: "I don't think it is a surprise so much to me.He is a strong professional, Joe.
"I can only really speak about what he did here and how he adjusted to what we offer the players here.
"He was first class and I felt that there is a 'student of the game' - to coin a phrase! - in him."
