This document contains details from a presentation by Portuguese soccer coach Carlos Carvalhal on defensive transition training drills. It describes 5 drills focused on improving a team's ability to recover possession immediately after losing it. Each drill is explained in terms of setup, objectives, and critical success factors such as reacting quickly, maintaining compact defensive shape, and transitioning between offense and defense. The concluding thoughts emphasize that defensive transition is difficult to train but important to master, as recovering the ball right after losing it often leads to goals. Players must learn to both directly pursue the ball and occupy spaces depending on the situation.
