4) Wales
When discussing dark horses, one cannot fail to mention everyone’s favourite at the moment, Wales.
It almost seems a mistake to even label them as an underdog, as they are currently 15th in the Fifa World Rankings, six places below England.
They finished in Group B, behind Belgium, and have undoubtedly one of the best attacking players in the world in Real Madrid’s Gareth Bale, as well as Arsenal midfield maestro Aaron Ramsey.
With those two and a close-knit squad, they will always have a chance and could well challenge the giants in Europe in June.
