During an open team practice before the 2002 FIFA World Cup, Ljungberg broke into a fight with teammate Olof Mellberg following a robust tackle from the latter. Ljungberg pushed Mellberg right in front of the world press and Mellberg responded by grabbing at Ljungberg's jersey top at throat level before the two wrestled on the ground. The two of them were quickly separated by shocked teammates and the team practice was immediately cancelled to deal with the public relations disaster. Within hours, video footage of the fight flooded the media and internet.
