Speculation is rife as to who should make the cut for their country, but when will we know for sure which players will participate?
The 2018 FIFA World Cup in Russia begins on June 14 and ends on July 15, with 32 squads from around the globe taking part in football's most prestigious tournament.
Of the 32 teams taking part, 20 of those will be making back-to-back appearances, including reigning champions Germany, while less recognised national sides such as Iceland and Panama are making their first appearances.
Similarly, fans of the beautiful game will see star household names such as Lionel Messi and Cristiano Ronaldo represent their respective countries, but will also have the privilege of discovering new faces as coaches look to break in a new generation of younger players.
