What's this about choice?
Now obviously you woudn't handle it like that. He has a tremendous amount of international experience so it makes sense to get his thoughts about the situation beforehand - you wouldn't be a good manager or a leader if you didn't listen to your teammates, especially ones with a lot more experience than you. But you listen to him, and he either changes your mind (if he tries),or he doesn't. Then you make a decision and he goes wherever you tell him. In the end, as long as you have the job, you have to do what you think is best to win.
FTR, I don't really see the value in this particular change, but your primarily responsibility isn't to any one player.
