Rumours are swirling around Natan, with Chelsea reportedly showing interest in the defender currently plying his trade at Real Betis. With both teams looking to strengthen their squads, the move could have a massive impact on their seasons going forward. Manchester United and Barcelona are reportedly waiting in the wings. Finalising a fee and payment terms remains central to closing the transfer. So far in this season, Chelsea are conceding 1.86 goals a game (13 in 7), more than they'd like compared to the Premier League standard. The hope is Natan adds a bit of steel and helps make them tougher to break down. Real Betis continue to be linked with Raphinha while Chelsea are also rumoured to be tracking Daniel Banjaqui, Malik Jakupovic and Andy Diouf. Looking for Chelsea transfer rumours?
