Nike launched a key battle in its war for shirt supremacy on Sunday (November 24) with the unveiling of the kit Brazil will wear as hosts of the 2014 World Cup.

VfL. Wolfsburg midfielder Luiz Gustavo appeared in Copacabana wearing the famous yellow shirt the team hopes to take all the way to the final at Rio de Janeiro's Maracana in July.

The Brazil shirt is Nike's top selling international jersey and the company said it does a billion dollars of business in Brazil.

Nike expects Brazil to be its third largest market in the world by 2017, behind only the United States and China.

Nike said the new jersey is the lightest ever.

One of the features is of course the Brazilian Football Confederation emblem which features five stars for each of the yellow and gold's five World Cup championships.

Coach Luiz Felipe Scolari said his side was planning to add a sixth star with a record sixth championship adding that his team was ready for whatever teams they are put up against when the tournament gets underway in Sao Paulo on June 12.

Nike also helped organize a day of sport activities around the unveiling of the team's uniform which included youth football games, a 5 and 10K run and skateboarding sessions in addition to local musical acts.
