Yeah I don't put any blame on the new and young kids. Potential and level can be discussed sure.
But Dest for example shouldn't be excecuted because of his slip yesterday. Shit like that happens.
Behind him there should've been another two veteran safety nets: Pique missed his marking and ter Stegen missed his near post. Dest's fuckup should've been prevented by those who are supposed to be reliable when youngsters aren't.
