Chelsea's transfer window is finally well underway. The addition of Raheem Sterling was a statement signing for Thomas Tuchel's squad and the German coach will be relieved to have a second player in the form of Kalidou Koulibaly arrive in the USA.
The Blues may still require more defensive reinforcements following the departures of Antonio Rudiger and Andreas Christensen earlier this summer, with Presnel Kimpembe now seemingly the club's main target. Indeed, the Blues may even sign three central defenders.
Tuchel said earlier this week: "We need some centre-backs – at least two to replace Andreas and Toni. We have Azpi (Cesar Azpilicueta) at the moment in our squad, and we plan with him, but there are talks going on about his personal situation and what we want. We will be very open with you, so that makes it three."
