Victor Lindelof has a £25million release clause
The Blues were linked with a move for the Sweden international throughout the summer transfer window.
However Antonio Conte eventually turned to David Luiz to bolster his defence, bringing the Brazilian back to Stamford Bridge from PSG in a £32million deal.
But according to Football Italia, Conte still wants to add to his defensive options in January and will move for Lindelof.
However, the report adds the Blues face competition from Inter and PSG for the 22-year-old who has a £25million release cause.
Lindelof burst on to the scene at Benfica last year, and he has continued his fine form this season, starting all of the Portuguese club's games in the new campaign.
The centre-back has six caps for Sweden and was part of Janne Andersson's squad for Euro 2016.
