I'm not sure I've watched Caden Voice before other than *that* challenge (still got mixed feelings on us sticking by him, young kid or not) but I have watched Alfie Pond and asking him to play the ball out is just daft, he's much more Paul Butler than Paul McGrath. Concentrate on what they can do, not what they can't.
Rewind 20 years or so and look at two of England's best centre halves. Rio Ferdinand and Jamie Carragher. Why would you ask the latter to play like the former, it would be ridiculous, he can't do it. He's a superb defender, leave him to do that. Not keen on a one size fits all approach at youth level, you should be able to spot where a player sits by their late teens. In fact Pond is 20, not sure what they think he's going to turn into from here.
