I am looking forward to the next part, especially how the possession regain graph is going to change for your team. I wonder if this can change at all without having better players (or growing reputation), or most of it is just down to the formation that we use? I used to use a deep formation but with heavy pressing and I also noticed that the team is mostly getting the ball back around the halfway line.
This is I think one of the less discussed parts of a possession tactic, where you loose the ball usually and how does that influence you getting it back. So mostly I would look to make it so that the team looses the ball in advanced areas, in the final third preferably around the touchline, I think that is the best for loosing the ball. Losing possession in the final third is also miles better than loosing it in the middle of the park, I think loosing the ball around the halfway line makes it impossible to get it back without conceding a shot/possession.
So I guess my point is that (I think) the further up the field you loose the ball most of the time, the better chance you will have at getting it back, so I am looking forward to how it will change for your team.
