The 29-year old has been in talks with the Trotters over the last few days about a move to the Reebok Stadium following his release from Italian giants Inter Milan.
Fadiga who has also played for Auxerre and Standard Liege, shot to prominence in his country's 2002 World Cup campaign in Japan & Korea where he lined up alongside current Wanderers loanee El-Hadji Diouf in a Senegal team that managed to defeat the then holders France at the start of the group stages.
