It's one of those cliches that someone can play "all across" a line.
You see it for both attack and defence.
In reality, the player either never plays one of the positions or would be pretty darn average there,
Any idea of paying huge wad for Grealish and then shoehorning him into right wing would show we haven't learnt another lesson of recent years.
We are definitely learning on things like not pursuing late 20/30s superstars, so i'm sure we won't try and shoehorn Grealish in, irrespective of the Sancho end result.
