I dunno why people take it so personally when this sort of stuff occurs. Kyle Walker isn't your son or your brother. He is a millionaire footballer, and he would most probably step over you if you were face down in the street. In a few years from now, you'll barely recall his name.
You have no control or influence over anything that a city player does. Let the people who employ him, deal with him. It is not your burden to get all hot and bothered about.
Stick to the football, and let the tabloids roll around in the gutter.
