Sivasspor have appointed former Brazil and Real Madrid full-back Roberto Carlos as their new head coach on a two-year contract.
The 40-year-old - a World Cup winner in 2002 - has assumed control of the Turkish Super Lig side after leaving his role as director of football with ambitious Russian outfit Anzhi Makhachkala.
He retired from playing following a brief spell as interim boss of Anzhi in early 2012 and, having spent the last year working behind the scenes for Guus Hiddink, he has assumed his first full-time coaching role.
During his unveiling ceremony at the Sivas 4 Eylul Stadium, he told the club's official website: "This is one of the most important days of my life.
"I'm pleased to be here and first of all I want to thank the president (Mecnun Odyakmaz) for giving me this chance.
"This will be a team effort and we have lofty ambitions. I would like to see the stadium full for every game while we strive to bring success on the field."
Sivasspor have enjoyed mixed success since their arrival in the top flight in 2005, winning the championship in 2009 but steadily falling away to finish 12th in the recently concluded campaign.
Cesar Domingos becomes his compatriot's assistant manager while former Sivasspor midfielder Murat Erdogan takes over as director of football.
A former left-back with Inter Milan, Palmeiras and Uniao Sao Joao, Roberto Carlos has previous experience of the Super Lig having represented Fenerbahce 66 times between 2007 and 2009.
His time in Istanbul was preceded by a brief return to Brazil and Corinthians before he joined big-spending Anzhi in February 2011.
But he is best known for his time in Madrid - where he won four Primera Division titles, three Champions League trophies, the UEFA Super Cup and the Intercontinental Cup - and for scoring with a wickedly curling free-kick from almost 40 yards against France in 1997.
