Query: Lack relevant information

As one reviewer rightfully said,it lacks info on how to make the system work and merely focuses on attacking schemes only.It lacks clarity as to the roles and fucntion of the midfielders,attackers and wingers.The videos largely focuses on the role of the wingbacks and their over-lapping runs,that's all.This w3as the only good aspect of the video and has some clear drills on how to implement that aspect only.
