How did you feel about that @Snow ? Was it a bit of a downer or was he still a 'bit of a lad'?I can confidently say that there are semi pro footballers who work harder than many professional footballers. Sancho can't keep his job as a footballer. He couldn't work a full day job and then practice in the evenings and compete on the weekend.
Working hard as a teenager where you dismiss school and don't have responsibilities is a privileged life. Then you reach a point where you have to play against adults, adults who don't muck around. You get responsibilities. That's where professional players get separated from the likes of Sancho, Morrison, Adu etc. All the talent in the world won't do you much good if you don't have the head for professional football and when you take everything for granted.
I saw a 32 year old Premier League winner Lee Sharpe play football against semi-pros and he was consistently the worst footballer on the pitch. That's what happens when your head is gone.
