As many as 250 ethnic groups have been distinguished and named. The most numerous people are the Kongo, Luba, and Mongo. Although 700 local languages and dialects are spoken, the linguistic variety is bridged both by the use of French and the intermediary languages Kikongo, Tshiluba, Swahili, and Lingala.
LuaLua was born in Kinshasa but moved to the United Kingdom at a young age. After impressing in a college football match, he signed for Colchester United. There he scored a total of 21 goals in 68 appearances which prompted Newcastle United to sign him. However, the competition for places meant he was less of a regular in the first team and after four seasons and 88 appearances there he transferred to Portsmouth, the club that had previously loaned him for three months while at Newcastle. He remained there for three seasons but his spell was marred by disciplinary problems and malaria. After this, he moved to Greek club Olympiakos and spent a season there, helping them to win their fourth straight Super League Greece title, before joining Al-Arabi in 2008. LuaLua received his first cap in 2002, and has since represented his national team in the 2004 and 2006 Africa Cup of Nations.
