Chelsea trio Oscar, David Luiz and Ramires could all feature for the Selecao, as could Tottenham midfielder Paulinho.
Familiar faces which could be in the Croatia line-up include former Tottenham midfielder Luka Modric, Everton striker Nikica Jelavic and Southampton centre-back Dejan Lovren. Croatia finished third in their first World Cup finals in 1998 but have won just one match since.
Spain have won their last three major tournaments and head to Brazil hoping to become the first European team to win a World Cup on South American soil.
But manager Vicente Del Bosque saw his team handed arguably the toughest of the groups in Group B, as Spain were placed up against
2010 finalists Netherlands
The Dutch won nine of 10 qualifying games and still have the core of the side which reached the final in South Africa, with Manchester United striker Robin van Persie and Bayern Munich forward Arjen Robben in lethal form for their clubs.
Chile, meanwhile, pushed Spain all the way for their
2-1 win in the group stage
four years ago and beat England comfortably at Wembley last month.
The champions' task is made harder by the fact that the runners-up in their group are likely to face Brazil in the last 16.
England's Amazon assignment
England were hoping not to visit the Amazon jungle during their time in Brazil, but instead they will have to face four-times winner Italy in their opening match in Manaus in sweltering temperatures of 30C.
As if that task was not daunting enough, Roy Hodgson's boys have been told they are not welcome in Manaus because of Hodgson's comments before the draw, where he stated a trip north would not be ideal. England should probably prepare for a fiery welcome to the jungle.
However, England's preparations for the tournament are expected to include two matches in the United States, where Hodgson will base his team in the humidity of Miami.
But with Italy experiencing the heat of Brazil during last summer's Confederations Cup, England could be left sweating on progress from Group D.
Fortune favours the French
France needed a play-off win against Ukraine to qualify for the finals
If the draw followed the same procedures as in 2006, France, as the lowest-ranked team to qualify from Europe, would have been placed in a group with one of the seeded teams from South America. Instead, the format for the draw was changed and it was Italy who ended up in with Uruguay and England.
The French? They will surely fancy their chances of qualifying from a group containing Switzerland, Ecuador and Honduras. "It's true, I won't hide it from you, it could have been tougher," said France coach Didier Deschamps.
The 1998 champions finished bottom of their group in the last World Cup but with a potential second-round tie against either Nigeria or Bosnia-Hercegovina on the cards, Deschamps' men could be dark horses for a shot in Brazil.
Messi and Ronaldo go for greatness
With over 300 goals for Barcelona, four Ballon d'or awards, six La Liga titles and three Champions League winners' medals to his name, Lionel Messi has arguably already cemented his place among the sport's all-time greats.
Alongside Cristiano Ronaldo, he has dominated Spanish and European football for the last four seasons.
Euro 2012 highlights: Ronaldo shines against the Netherlands
But a World Cup title eludes the duo, and their individual records are poor. Messi has scored just once in a World Cup finals match for Argentina -
the sixth in a 6-0 thrashing of Serbia
in Germany - while Portugal captain Ronaldo can only claim goals against Iran and

a hat-trick against Brazil
last summer and has finally brought his club form to Argentina, with his record now an impressive 37 goals in 83 caps.
With Messi facing Iran, Bosnia and Nigeria in Group F, and Ronaldo's Portugal up against Germany, Ghana and the United States in Group G, both players will hope that they can lead their sides to glory next summer.
