When the shape changes, do not try to redraw all eleven positions immediately. Find what has changed in your relationships.
If you move from a 4-3-3 to a 4-2-3-1, ask: who is now alongside me, who is ahead of me, and which space am I responsible for protecting when we lose the ball? Those answers are more useful than thinking about the formation name.
Also listen for what the manager is trying to solve. The change may be about creating an extra player next to you, protecting a lead or getting a number 10 higher. That tells you what behaviour should change.
Use the first stoppage to confirm one point with the nearest midfielder if needed.
Experienced tactical players are not the ones who memorise every diagram fastest. They identify the two or three relationships that have actually changed and adjust those first.
