Chelsea could still have multiple changes still to their backline before the September deadline despite the Kalidou Koulibaly signing.
In a summer that has seen Andreas Christensen and Antonio Rudiger already leave for La Liga and Marcos Alonso soon to follow the pair to the same league, manager Thomas Tuchel has had to put the large majority of the transfer budget to revamping the defence.
Koulibaly and Marc Cucurella's additions have gone some way to fixing these issues caused by the exodus of the aforementioned trio but the age profile of this current Blues defence has Tuchel slightly worried, meaning Leicester's Wesley Fofana is much needed, even if it will cost a world-record fee.
