You may be right. Personally I think it's a hell of a jump from seeing him on that documentary and seeing his twitter posts etc and concluding from that that he'd rather be on a reality show than a professional footballer.I know the documentary cannot be taken too much as a guideline but to me he did come over in that as a somewhat immature individual using his boyish charm to try to impress his team mates and manager. His media posts too always seem to illustrate someone who is reluctant to accept the fact he has to grow up.
I realise he's still a relatively young man but I just don't see a person willing to devote the time and effort required to make it to the top as a footballer in the same way that Son does for example. He relies more on his personality than his ability to carry him through and now under Jose he's getting found out.
Just my opinion of course but there it is.
Judge his performances as poor, by all means, but making guesses about his personality and motivation seems very harsh to me.
