Oh yes, I was clearly terribly upset by the discussion, and in particular that it was in the GF thread.
By all means, discuss the goal. He ran straight down the middle of the pitch and finished well. Lacazette could absolutely do it, and your suggestion that he somehow could never have accomplished that is certainly wrong.
His touch is not average. You clearly haven't really watched him, or have some weird bias. His touch is excellent, and he's much more of a proven top striker than Morata because he's scored a fuckton more goals than Morata ever has. That's just a fact, there's no debate to be had.
I don't mean to say Laca is a better all-round footballer, that's a different story.
