Adailton Pereira Dos Santos is currently having trials at a club in Finland. Previously many seasons in the Tunisian league. Apparently, despite being born i Brazil, he's played a few internationals for Tunisia.
I dont think he played any internationals for Tunisia. I think you are mixing him up with Tunisia's Brazilian striker Franciledu Dos Santos (pardon the spelling) who currently plays for FC Sochaux, and used to play in the Tunisian league.
