Besiktas striker Bebe has been forced to train separately from the club's squad as boss Tayfur Havutcu is reportedly unhappy with his attitude.
The former Manchester United man has been excluded from squad training, along with Sidnei and Julio Alves, due to "a lack of discipline and issues with their personal lives", the club's official website states.
Bebe joined Manchester United from Vitoria de Guimaraes in 2010, before departing for Turkey a year later.
The 21-year-old has six Portuguese Under-21 caps to his name.
