Chelsea's transfer activities are continuing to pick up pace at rapid speed as the search for extra defenders for Thomas Tuchel's squad continues.
The Blues have already purchased Kalidou Koulibaly, who is likely to take the left centre-back spot in a back three, and have serious interest in Leicester's Wesley Fofana and also Joska Gvardiol from RB Leipzig. The huge prices on both players' heads hasn't put Todd Boehly off yet as Chelsea turn to more defensive targets.
This is all important for Tuchel due to losing Antonio Rudiger and Andreas Christensen on free contracts at the end of last season and also the failed attempts to sign Jules Kounde. The uncertain commitment and mindset of Cesar Azpilicueta and Marcos Alonso, as well as interest in Levi Colwill, makes the foundations of Chelsea's team very thin.
