I think Richarlison is that player personally.
Difficult to know with Moura, he's been a decent option at times. But now injured for a while and definitely not a great fit.
Perhaps Gil doing well means that there's less pressure on a short term attacking solution at least. Doesn't have to be someone ready made.
If our interest in Malinovskyi was real that would explain us "letting him move" without pushing for him.
Son, Kane, Kulusevski, Richarlison, Gil +1 would be good. Looks a bit light with just those 5. But no idea who that one player should be.
