Lenglet's profile shows how important a ball-playing left-footed CB is for our system, especially in a back 3. He is one of the best CBs in the world with the ball at his feet, releasing fast drilled passes and breaking lines. It's a pity he always has multiple brainfarts in him and isn't able to fucking not use his hands while playing football. A right-footed CB at LCB could work (like Masche), but when the opponent presses while knowing the LCB can't use his left foot, they could cut out the passing lanes to the left wing and force turnovers more easily. If we continue with a back 3, a left-footed CB is a must. If we play with 2 CBs, we could do with a right-footed one.
