The "Group of Death" may simply be the one with the strongest teams, or the most strong teams. Using FIFA World Rankings as a measure of the strength of the teams, "The Guardian" calculated in 2007 that the strongest "Group of Death" was Euro 1996 Group C. The teams (and world rankings) were Germany (2), Russia (3), Italy (7) and the Czech Republic (10). This record was exceeded by the May 2012 rankings for Euro 2012 Group B, with Germany (2), the Netherlands (4), Portugal (5) and Denmark (10), but not the June rankings immediately before the tournament (3, 4, 10 and 9 respectively) In women's football, 2007 World Cup Group B featured three of the top five teams in the FIFA Women's World Rankings entering the tournament – the United States (1), Sweden (3) and North Korea (5) – with Nigeria (24) being the "minnows".
