Sweeper have to protect the keeper he/she is just behind the center back/center backs and in front of the goalkeeper
There are not players officially designated to protect the goal keeper, but as in other sports (e.g. ice hockey) there is an unwritten rule that teammates (especially fullbacks) protect the goalkeeper. This is due to the fact that the goalkeeper is put in the most vulnerable situations (spending a lot of time on the ground, in close proximity to the ball, and legs intent on kicking the ball). Players do not have special privileges within the rules to protect the goalkeeper, but expect them to do so.
Defenders assist the goalkeeper.
