The bid evaluation report stated: "The Russian bid proposes 13 host cities and 16 stadiums, thus exceeding FIFA's minimum requirement.
The 22-member FIFA Executive Committee convened in Zürich on 2 December 2010 to vote to select the hosts of both tournaments.
Both Iceland and Panama qualified for the first time, with the former becoming the smallest country in terms of population to reach the World Cup.
Other teams returning after absences of at least three tournaments include: Egypt, returning to the finals after their last appearance in 1990; Morocco, who last competed in 1998; Peru, returning after 1982; and Senegal, competing for the second time after reaching the quarter-finals in 2002.
From the preliminary squad, the team had to name a final squad of 23 players (three of whom must be goalkeepers) by 4 June.
Players in the final squad may be replaced for serious injury up to 24 hours prior to kickoff of the team's first match and such replacements do not need to have been named in the preliminary squad.
