I think it's less that and more his upbringing before pro football.None of us know what their personalities are like behind closed doors. It's childish to us but we haven't spent our whole lives being molly coddled by a system where everything is done for you.
Haven't hounded him exactly. I would say there's an argument that growing up would serve him well. Off and on the pitch.Then criticise him for his attitude to training, performances on the pitch etc, not this specific non-incident.
He probably does need to grow up, yes, and needs to play better, but I'm not going to hound him over this absolute non-story.
Doesn't mean he can't be a lad.
But as you could see in his meeting with mou in the doc, his petulance keeps him from taking advice to heart.
