No, of course, but he's not meant to. In the build-up phase, however, in terms of controlling tempo and slotting neat balls into channels and half-spaces, Jorginho is probably better than Partey and Xhaka. It is a skillset that isn't there at present, to that level.
For what it's worth, you should focus less on how you look to Chelsea fans (retirement FC) and more on how Arteta would utilise someone like him. Previous Chelsea disappointments don't represent this one. Every player is, ultimately, individual.
