From TheChels.info - The Chelsea Football Club Wiki
Baltemar José Oliveira Brito (born 9 January 1952 in Recife, Brazil) was an assistant first team coach at Chelsea between 2004 and 2007, during José Mourinho's first spell at the club. A Brazilian former defender who spent the majority of his playing career in Portugal, Brito first worked with Mourinho at União de Leiria, forming part of a backroom quartet (including Rui Faria, Silvino Louro and André Villas-Boas) that would eventually follow him to Chelsea. Among Brito's responsibilities at Chelsea was audio-visual work that would help prepare the team for matches.
When Mourinho left the club in September 2007 Brito parted ways with the Portuguese manager. He subsequently returned to Portugal and became manager of Second Division Belenenses in June 2010, but left the club before the season had started. He went on to manage in Libya and the United Arab Emirates before returning to his native Brazil, where he briefly managed Grêmio Osasco in 2013.
