I'm not overly surprised hes finally done something stupid. Phils been in the media eye since he was 15. Sports personality of the year at 16. City first team at 17, youngest PL winner in history, announced the golden child of English football. Settled down with a long term girlfriend and a kid at 19, and all the stories about how all he does in his spare time is fish with his dad. He was dealing with everything a little too perfectly and a mistake was inevitable.
Hes lost out on being an adolescent, doing stupid things and learning from them without the whole world seeing it.
All things considered its not the worst thing in the world to have happened to him. Better a small incident at 20 to learn from than bottling it all up and being a tiger woods/giggs at 32.
Greenwood being there halves the spotlight and rules out any club rivalries exacerbating the backlash. The club is taking it seriously and he'll learn from it.
