The talk of incoming players will disrupt several of Chelsea’s Champions League winning team and send messages to those in their loan group and academy.
Chelsea are open to selling Tammy Abraham but they have initially asked for £40 million ($57m) which has risked pricing out interested clubs including West Ham and Leicester City.
Would Olivier Giroud stay in Chelsea?
Olivier Giroud has had a one-year extension clause activated on his expiring deal but remains intent on pushing for a move, with AC Milan previously keen to sign him on a free transfer.
Michy Batshauyi has seen Leeds United lose interest over a transfer, with the Blues asking for around £15m ($21m).
Youngster Armando Broja is likely to be among players who get the chance to impress Thomas Tuchel in pre-season after a year on loan at Vitesse.
Tino Livramento has been contacted by AC Milan but Aston Villa are among clubs that seem more viable options for the young full-back, whose future could be thrown into doubt by signing Hakimi.
Callum Hudson-Odoi is rumoured to be attracting renewed interest from Bayern Munich, but any move is off the table unless Chelsea opt to sell him. For now, no such conversation has been had.
