Stéphane Mbia Etoundi is a Cameroonian football player who plays for French League 1 club Olympique Marseille.
Stéphane began his playing career at the famous Kadji Sports Academy in Douala, Cameroon where fellow Cameroon internationals Samuel Eto'o, Carlos Kameni and Eric Djemba Djemba played.
In 2004 he moved to France, to join Stade Rennais. Mbia emerged into the Rennes first team in the 2005–06 season, making a handful of appearances.
The Cameroonian scored his first Ligue 1 goal for the club in November 2006 against champions Olympique Lyonnais. On the 14th July 2009, M'Bia completed his £10.4 million move to Marseille from Rennes.
He participated in winning the French Ligue 1, being replaced at mid-season in a centre back position, along with his team mate Souleymane Diawara.
His repositioning as a center back was a success and he played the rest of the season at this position, where he is now considered to be one of the best performer in Didier Deschamps' squad.
Mbia played international football at junior level for Cameroon. He was part of the Cameroon squad for the 2003 FIFA U-17 World Championship in Finland, where his side were eliminated in the group stage. He made his debut for the Cameroon national team in 2005.
He was part of the squad for the 2008 Africa Cup of Nations in Ghana, where Mbia scored twice against Tunisia in the quarterfinal.
Mbia was part of the Cameroon squad for the 2008 Olympics in China, playing in all four of his teams matches, and scoring once against Honduras.
