Beat a defender with the croqueta. Drive at him to make him commit, shift the ball quickly across the body from one foot to the other, and accelerate past on the far side.
The player drives at a defender, then plays a croqueta, a quick shift of the ball from one foot to the other across the body, the instant the defender commits, and accelerates away on the far side. Emphasise driving at the man first, a small sharp shift, and the acceleration after. Practise both directions. Rotate the roles.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
