The coach of Burnley is a coach that was once a player in Manchester City, I do not know how that is supposed to give him an advantage, but that is some kind of advantage I think. Also you cannot underestimate teams that are fresh from relegation, sometimes their blood is hot, and with that motivation of being in the premier league can make them want to win the reigning premier league champions as a big statement. They can do it if Manchester City do not put up a good performance. There is also the advantage that they are playing this game at home in front of their supporters, that can help give them morale and boost.
