4. Wales
Wales’ hopes of qualifying for the World Cup shattered after the defeat against the Republic of Ireland.
Having scaled new heights with their historic run to the Euro 2016 semi-finals, Wales started this campaign with the unfamiliar status of being favourites. They were among the top seeds.
Although Group D always had the potential to be one of the tightest and most competitive in Europe, it did present Wales with a fine opportunity to qualify.
Coleman’s side drew half of their games, squandering the lead in four of those five fixtures. It left themselves with too much work to do in the closing stages of the campaign.
