I understand the importance and differentials between the two, but have they always been so strict?
I see so many people talk about how stupid some people are suggesting RCB’s to play LCB and vice versa, but I can’t remember previous generations being so limited, though perhaps that’s due to the lesser responsibility on ball playing duties?
It’s not essential to have a left footed centre back paired with a right footed CB but it helps. Modern thinkers of the game like Wenger and Guardiola like(d) to have left footed CBs in their squads.
