I'm not sure if all of the players you mentioned will be sold, or if Chelsea will be willing to sell them. Raheem Sterling, Nicholas Jackson, and Noni Madueke, for example, I believe later joined Arsenal. As of right now, I'm really impressed with Chelsea's ability to make a lot of money from their sales; they seem to have good business sense and talent selection skills. It should also be interesting to see how these transfers will affect Chelsea's future and the careers of the players involved. Chelsea is actively managing their squad, bulling and selling players to maximise profits and build strong terms.
