The Bulgarian club CSKA is among the teams interested in Portuguese right-back Zé Carlos, a 27-year-old free agent whose contract with Gil Vicente has expired. Clubs from the Championship are also interested in signing him. In addition to CSKA, the Greek team Volos has also inquired about the former Gil Vicente captain. Both CSKA Sofia and Volos have made approaches, though England is currently considered the most probable destination for the player.
