If the transfer of the young defender, who is claimed to have reached a 4-year deal with Beşiktaş, becomes official, the black-and-whites may experience a separation.
According to the news in Milliyet, Kartal is making calculations of parting ways with Welinton Souza or Francisco Montero after the transfer of Isak Hien.
Black-and-whites, who want to act in financial discipline in the transfer, are planning to send Welinton as a rental and Montero with his testimonial.
