"Almeida was a star of the lengthy semi-final against the USA and is a major reason for his team's presence in the final."
-- Ginny Weasley's team overview in the Daily Prophet, 11 July 2014 (Pm)
As the Brazilian team's Keeper at the Quidditch World Cup 2014 tournament, Almeida was key to Brazil's victory over the USA in the semi-final, repeatedly stopping the American Chasers from scoring, thus allowing the match to be decided by Tony Silva's Snitch catch. He also played well in the team's earlier matches against Haiti and Wales (Pm).
Only the brilliance of Bulgarian Seeker Viktor Krum allowed Bulgaria to beat Brazil in the final. As the Brazilians are such a youthful team, however, they are expected to be able to compete again at the next Quidditch World Cup in four years time (Pm).
