The volleyball use is younger.nounA central defender to whom no forward is assigned for marking, forming the last line of defence and often initiating the offensive play.“Nicknamed “Der Kaiser”, Beckenbauer was as elegant as he was dominant, and such was his assurance in possession that he came to master the modern sweeper role, or libero. More so, he is credited with creating it.”A designated back-row player intended to be used as a ball-control specialist.
