Chelsea are credited with an interest in Bayer Leverkusen defender Piero Hincapie who impressed for Ecuador at the World Cup in Qatar.
The Blues have a long-standing interest in signing RB Leipzig centre-back Josko Gvardiol they will face intense competition to land his signature with the likes of Manchester City and Real Madrid also in the mix.
According to a report from Sky Sports, it is claimed that should Chelsea miss out on Gvardiol, Leverkusen centre-back Hincapie will emerge as their backup plan with Graham Potter looking to reinforce his backline.
Despite spending £75 million on Wesley Fofana and £33m on Kalidou Koulibaly in the summer to bring in two highly-rated defensive names, Chelsea appear intent on improving their options at the back heading into the upcoming January transfer window.
Chelsea co-owner and acting sporting director Todd Boehly is ready to provide Potter with the financial backing with the former keen to bolster the Stamford Bridge squad which has failed to meet expectations so far this season.
