Igor Vinicius, currently with Santos, is the latest name linked with a potential switch to Barcelona. The defender could become a key signing should the move materialise, as the club seeks to strengthen in a key area of the pitch. Newcastle and Chelsea are reportedly waiting in the wings. Finalising a fee and payment terms remains central to closing the transfer. Barcelona's back line has been a real strength this season, conceding just 1.11 goals per game (20 in 18). Igor Vinicius would be expected to slot into that unit and hold his own in an already solid setup. Reports suggest Barcelona are monitoring Bernardo Silva, Branimir Mlacic and Joao Cancelo whereas Santos have not been associated with other players at this stage.
