I agree that Potter and Tuchel is not so far in term of quality, but I mean Tuchel already has his time and chance to proof himself, and I think it's not wrong for Tood Boehly to give another coach a chance with Chelsea. And I don't know what you mean by Chelsea didn't get any superstars, Sterling is quite a superstars in Premiere League.
actually i don't think that potter will be able to bring chelsea much better than tuchel because potter is ex-brighton & hove coach, but the development of the team is not better
todd and behdad said that they believe potter is a long-term project to build chelsea to be better, we'll see what achievements potter can give chelsea
