Cameroon
Cameroon were the surprise winners of the Africa Cup of Nations in February. That triumph represented their first silverware in 15 years and secured them a place at the Confederations Cup, where they were runners-up in their last appearance back in 2002.
Hugo Broos became Cameroon's head coach in February 2016 after applying for the position online. A year later, the former Belgian international defender led them to success in the Africa Cup of Nations with a strong defensive platform and sufficient attacking potency to drive them past Senegal, Ghana and Egypt on route to lifting the trophy.
The large majority of that squad are back for this summer's tournament. Although it will be very difficult for them to progress from a group that features both Chile and Germany, Cameroon are nevertheless the most likely of the remaining teams to cause an upset in Russia.
