England has complained to FIFA that one of its fans got into the team dressing room after the 0-0 draw with Algeria and had angry words with David Beckham.
Many of the 25,000 England fans in the Green Point Stadium booed the players off the field after Friday's poor performance, which left the team in danger of being eliminated at the group stage.
The Football Association said it had complained that one fan managed to get through security and into the dressing room.
The FA said it would put the complaint to FIFA in writing. Although Beckham is not fit to be in the squad, he has been traveling with the team.
