As the memories of Euro 2016 start to fade, the world of international football will now focus on the upcoming World Cup qualifiers. Ireland, Northern Ireland and especially Wales can look back on an amazing Euros campaign after exceeding all expectations and lighting up the tournament with their great sportsmanship, enthusiastic singing and (not forgetting) some wonderful, amusing and colourful flags! As for England….least said soonest mended. With Big Sam now in charge one things for sure – he can’t possibly do any worse.

The 21st FIFA World Cup will be held in Russia from the 14th June to the 15th July 2018 with 32 participating nations (31 qualifiers plus the host nation). Russia was given the honour of hosting the competition after being awarded the hosting rights on the 2nd December 2010 by the twenty-two-member FIFA Executive Committee in Zürich. The last World Cup to be held in Europe was in 2006 (Germany).

European qualifiers for the long road to Russia will start on September 4th 2016, but in other parts of the world, the qualifying process for Russia 2018 started as early as March 2015 (Central America and the Caribbean are already on round 4 of the qualifications).  The different federations around the world have varying formats for qualification to the 2018 World Cup, so some continents will endeavor a much more long and drawn out process.
