Tunisia international Francileudo dos Santos has apologised to Tunisian football fans for draping himself in a Brazilian flag.

The Sochaux striker celebrated his French club's League Cup success in April with a banner from his original homeland.

The Brazilian-born striker obtained Tunisian citizenship last December, since he had spent two years in the north African nation playing for Etoile du Sahel before moving to France in 2000.

Dos Santos was a key player in the Carthage Eagles' inaugural Cup of Nations success earlier this year, but celebrated Sochaux's League Cup triumph with a Brazil flag.

"I admit that this was not a wise decision from me," the 25-year-old told a Pan-Arab satellite channel in an interview.

"I should have put into consideration the feeling of the Tunisian fans."

"It was a mistake and I promise to be more considerate next time."

Sochaux beat Ligue 1 rivals Nantes on penalties to win the final and Dos Santos' post-match antics infuriated Tunisia's national media.

They accused the player of humiliating and disrespecting his adopted nationality.

Dos Santos was a hero for hosts Tunisia in the Nations Cup finals where he scored four goals, including the Carthage Eagles' opener goal in their 2-1 victory over Morocco in the final.

The Sochaux striker is the second Brazilian-born player to be adopted by Tunisia after Jose Clayton, with the Esperance defender having played in the last two World Cup finals for the African nation.
