Took this from the Morata transfer thread - I don't know if that tweet is legit, it seems to go back to Balague. But supposed it is, it describes a situation that has been anticipated here already.
As I said before, I'm convinced Morata would allow Conte to continue the interplay-oriented offensive approach he has taken so far, while I fear Lukaku would severely change the balance of the front three. Morata is also way more active defensively, which I'm sure Conte is looking for too. He obviously knows what he's doing, and I think it would be a mistake to enforce a player upon him that he deems to be less effective in his setup than other options.
But it's transfer news season, so it's probably better to wait if these claims will be substantiated or not.
