If we had a manager who thought like that.... we would not have that manager for long.It would be nice however if we had a manager with enough foresight to maybe sacrifice his best side on occasion to have a better side down the road. This situation is like if Martinez had used Leon Osman over Barkley. I doubt Barkley would have reacted well tbh.
