RIO DE JANEIRO, Aug 8 (Reuters) - Brazil are to play Wales in a friendly in London and have changed the date of their game against Argentina in the same city. The Brazilian Football Confederation (CBF) said on Tuesday that the match against arch-rivals Argentina would be on Sept. 3 at Arsenal's stadium and not Sept. 2 as previously announced. Brazil will then face Wales at Tottenham's White Hart Lane ground on Sept. 5, the CBF said on its official website. Brazil's first game under new coach Dunga, who replaced Carlos Alberto Parreira after the World Cup, will be against Norway in Oslo on Aug. 16. The match against Argentina will be the first for their opponents under new coach Alfio Basile, who has replaced Jose Pekerman. Brazil and Argentina were both knocked out in the World Cup quarter-finals. They last met in the Confederations Cup final in Germany last year with Brazil winning 4-1.
