The European section of the 2018 FIFA World Cup qualification will act as qualifiers for the 2018 FIFA World Cup, to be held in Russia, for national teams which are members of the Union of European Football Associations (UEFA). Apart from Russia, which qualify automatically as hosts, a total of 13 slots in the final tournament are available for UEFA teams.
The qualifying format was confirmed by the UEFA Executive Committee meeting on 22–23 March 2015 in Vienna.
Format
The qualification structure is as follows:
First round (group stage): The 52 teams will be divided into nine groups (seven groups of six teams and two groups of five teams) to play home-and-away round-robin matches. The winners of each group will qualify for the 2018 FIFA World Cup, and the eight best runners-up will advance to the second round (play-offs).
Second round (play-offs): The eight best runners-up from the first round will play home-and-away over two legs. The four winners will qualify for the 2018 FIFA World Cup.
Long wait for this one, doesn't start until Sept 2016.
