The point was that last season Watford were able to scout out a player in Brazil, sign him cheaply and now look like they are going to make a ludicrous profit on him.
That is what we used to do, before the structure of our club was professionalized / modernized / brought into the 21st century and we ended up throwing away tens of millions of pounds on players that we would be lucky to get half the money back on.
As for "the manager wants Richarlison" - why then are we only trying to get him in now, a couple of weeks before the season starts, and for a price that screams "panic buy"?
