THE World Cup is less than a month away and the squads have begun to roll in.

Everyone in Brazil breathed a sigh of relief as star striker Neymar was passed fit to take his place in their squad.

Sweden was torn over the will-he-won't-he debate over ageing superstar Zlatan Ibrahimovic - he won't, after all - and the final make-up of France's team is anybody's guess.

But here's what we know so far - every World Cup squad that has been announced as the days tick down to Russia's tournament-opening fixture with Saudi Arabia on June 15.

All nations will have to nominate a final 23-man squad by June 4 at the latest.
