Brazil are the overwhelming favourites to win Group AReuters

Group A is expected to be Brazil's to lose. The hosts will be desperate to finish at the top of the table, otherwise they stand a chance of playing against world champions Spain in the round of 16. Croatia look favoured to finish second behind Brazil, but Mexico, if they right Mexico show up, will have a chance, while you can never count out Cameroon, who do have a few individuals capable of putting in match-winning performances.
