The World Cup started in feverous fashion last night with the opening ceremony leading up to an entertaining clash between Brazil and Croatia.

A Marcelo own-goal saw the hosts go behind early on, only for Neymar and Oscar to make amends and set the Selecao rolling - but the referee's performance was the subject of much debate in the aftermath.

Yuichi Nishimura awarded Brazil a penalty for a foul on Fred when there appeared to be minimal contact and the Croatians were also unhappy when they had a goal ruled out for a push by Ivica Olic on goalkeeper Julio Cesar.

With Friday bringing the first full schedule of games, including a repeat of the 2010 final when Spain face the Netherlands, the other 30 nations now settle into the mood ahead of their first matches - with the likes of Mexico, Chile and United States particularly vocal on social media.
