Hungary
Hungary are somewhat fortunate to be in New Zealand - they lost two of their three qualifying matches and only scraped in - but shouldn't be underestimated. They have a promising roster, with several players at top European clubs, and reached the semifinals in their last appearance at this level (2009).
Favourites
Brazil and Nigeria. The yellow shirts will be keenly watched, as they bring their brand of "Samba soccer" to New Zealand's shores. The team adopted more of a defensive approach during their qualifying games, but still have plenty of flair. They should comfortably get out of a tricky group. Nigeria arrive in New Zealand as African champions, and will be expected to progress well into the later stages of the tournament.
Star man
Brazilian playmaker Andreas Pereira is one to watch. Based at Manchester United since the age of 15, he was named their under-21 player of the year last season and scored several vital goals for the youth team before making his Premier League debut in March.
Stat
Brazil last lifted the Under-20 World Cup in 2011, when three goals from Oscar (now a star at Chelsea) lifted them to a 3-2 over Portugal.
Did you know?
Nigeria have won the Under-17 World Cup more than any other country (four times), but have yet to repeat the success at the next level.
Prediction
Nigeria and Brazil should take the top two places (in that order) and the clash between North Korea and Hungary will likely decide third spot.
