The manager at Chelsea doesn't sign the players, as Conte liked to tell everybody. As for finding his replacement, if reports are to be believed then they found his replacement a long time ago and the delay in sacking Conte is most likely linked to the delay in reaching an agreement with Napoli for Sarri.
The appointment of a manager shouldn't effect their attempts to buy players though, if the above is the case.
I know, the point I was getting at was that given how little input the manager has, there's no reason to think they haven't made some headway with their transfer targets.
