There are just four weeks remaining of the summer transfer window and despite the additions of Kalidou Koulibaly, Raheem Sterling, Carney Chukwuemeka and Gabriel Slonina, Chelsea still have work to do. The departures of Antonio Rudiger and Andreas Christensen set the Blues up for a rebuild ahead of 2022/23 and that work still needs to be done.
While a number of players are still expected to leave, the Blues' focus remains on strengthening that backline. Wesley Fofana and Marc Cucurella are the subject of Todd Boehly's attempts to provide Thomas Tuchel with new tools.
football.london understand that Chelsea have agreed a fee worth £52.5million for the Spaniard, although the deal has yet to be fully signed off by the Seagulls. Things have not progressed so far with Fofana yet however.
