Referees are reminded that:

• it is an offence for a player to prevent a goalkeeper from releasing the ball from his hands.
  
  
• a player must be penalised for playing in a dangerous manner if he kicks or attempts to kick the ball when the goalkeeper is in the process of releasing it.
  
  
• it is an offence to restrict the movement of the goalkeeper by unfairly impeding him at the taking of a corner kick.

• It is not an offence if a player, with the ball under control within playing distance, screens the ball from an opponent without using his arms.
  
  
• If, however, he prevents an opponent challenging for the ball by illegal use of the hand, arm, legs or body, he must be penalised by a direct free kick, or a penalty kick if the offence was committed inside the penalty area.
