Coach Dad?

I have found it difficult sometimes to be the Coach and Dad to my 10-year old daughter, Genesis. I treat all my players equally and I have tried to keep "the game" and "the home" separate from each other. But it is really difficult. As a Coach, I can see all the potential she has for the game. She is quick to the ball, an excellent defender, and is starting to mature into a team leader. However, she is also lazy. The lazy part is what gives me fits as her Dad. During practice, she will just hang back and not pursue the ball. I, as the Coach, tell her to play up, but she still hangs back. When I tell her to listen and react to the situation, she takes it as an attack by her Dad and not the Coach just trying to make her a better player.
