Nah, this is probably close to the best we have right now at this age. We'll see what the U17 team looks like two years from now. Looking at how they did in the last tournament, I don't think they're keepers either.
In Argentina, whenever a new senior coach is named, they redo the entire management of the kids. It's re ed, but it happens. The current U20 coach is likely to be sacked once he's done with this compe ion. Things with the kids were better when one thing didn't depend on the other.
