Chelsea are primed for the return of their summer signing Christopher Nkunku this week.
The French attacking midfielder, who is a regular goalscorer, was training with the squad at Cobham.
The 52 million summer signing has been absent since he suffered a knee injury in preseason.
Nkunku is not expected to start against Newcastle United on Saturday, but may be on the bench.
Chelsea will manage Nkunku's return with extreme caution, as they have no desire to lose him for even longer.
Manager Mauricio Pochettino needs his creativity and goals to move the club up the table.
