5) Northern Ireland

Northern Ireland is a very small part of the United Kingdom but maintain a big talent of players that form a tough team to beat.
Michael O'Neill's side tasted major tournament football at last year's European Championships in France. They finished third in the group stages but qualified into the last 16 for being one of the best third placed teams. Wales knocked Northern Ireland out in a home nations encounter in the knockout stages
Yet again however the scene is possible for a Northern Ireland team to appear at the next World Cup in Russia. The Green and White Army are currently sitting in second place behind Germany and can mathematically finish either second or first.
It would be the first time Northern Ireland has appeared at a World Cup since Mexico 1986 where they finished 21st in the group stages. Overall the nation has been entered in three World Cup finals but the possibility of making a fourth global tournament is high.
