With the likes of Cristiano Ronaldo of Portugal, Spain's superstars and the surprises of Morocco and Iran, Group B has set the World Cup alight. Here are five things we have learned after the first round.
1. Cometh the hour, cometh the man
Portugal's captain and main man, Cristiano Ronaldo, became Europe's all-time highest international goal scorer with 85 goals overnight.
He has proved simply unstoppable in the first two matches, netting a hat-trick agaist Spain and burying a header to earn three points against Morocco. At 33-years-old, the reinvention of this astounding player only continues. He knows how to dominate in crucial moments and is the most prolific in front of goal.
Ronaldo is now more efficient at international level than ever before and the question remains, who are Portugal without him? And can he take them far in this tournament with his goal scoring nous?
2. Diego Costa proves crucial up front
Due to lack of experience up front, Spain needed a reliable target man. They won the 2010 World Cup with Fernando Torres and David Villa who boasted over 140 appearances between them at the time.
Costa has now scored with all three of his shots on target, and those goals were vital in Spain's draw against Portugal and triumph over Iran. Each passage of play with Costa at the end of it carries a potential threat of a menacing conclusion in front of goal.
3. Isco, the flawless dictator
The 26-year-old Spaniard was the conductor of play in the second half against Portugal. In full control he ran the show both with and without possession.
Against Iran, Isco saw more of the ball than any other player, completed an astonishing 92 per cent of passes and led the game in crosses with eight. Also a mention of most successful dribbles with nine. He helped defensively during Iran's threat and won the ball back the most. He was also a key part in breaking down Iran's tight defence, by weakening their resilience bit by bit. The best is yet to come.
