Unlikely, you'd have to be living under a rock not to know he's leaving this summer, it's not really news.
I suspect there's been extensive negotiations already and it's probably a lot closer than we realise. Romano saying we've had a bid ready since May and have just been waiting for the final to happen and Sullivan basically confirmed this.
It's the same with De Zerbi, mentioning unprompted that Caicedo will likely leave. In that case I'm guessing the certainty comes from whatever clauses were in his contract.
If you know a player is leaving, there's not much point in bluffing.
