Rumours are swirling around Igor Vinicius, with Chelsea reportedly showing interest in the defender currently plying his trade at Santos. With both teams looking to strengthen their squads, the move could have a massive impact on their seasons going forward. Chelsea remain optimistic, but the deal is not without hurdles. Barcelona and Newcastle continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. Chelsea's back line has been a real strength this season, conceding just 1.11 goals per game (21 in 19). Igor Vinicius would be expected to slot into that unit and hold his own in an already solid setup. Reports suggest Chelsea are monitoring Almugera Kabar, Bradley Barcola and Jeremy Jacquet whereas Santos have not been associated with other players at this stage.
