Chelsea have given permission to Borussia Dortmund to fly Carney Chukwuemeka and Aaron Anselmino to Germany to complete moves that will take player sales at Stamford Bridge this summer to beyond £270m.
Chukwuemeka, 21, spent the second half of last season on loan at Dortmund and is set to sign on a permanent basis for a fee of about £24m, with a significant sell-on clause included.
The England Under-20 international was keen to move back to the Westfalenstadion despite interest from RB Leizpig and is in the process of finalising his return.
That deal would take Chelsea's income from player sales this summer to a league-high £273.
