Definition of centre back

"Centre back" is a relatively recent term, emerging in the late 20th century, It reflects the evolution of football tactics. In earlier eras, defenders were often labeled simply as "backs" or "full-backs." As the game became more sophisticated, the central defensive role became more specialized. The term "centre back" emerged to distinguish those players who primarily operate in the center of the defense from full-backs, who play on the flanks. This reflects the central position's critical role in stopping attacks and protecting the goal.
