Watford boss Marco Silva admits they need a work permit for Richarlison.
For the draw with Real Sociedad, new signing Richarlison was an onlooker from the stands as he awaits a work permit to join the club, and Silva is hopeful of making him his next addition.
He said: "We need to wait for a work permit, but at the moment he's not your player.
"If everything goes ok, he can come to us and play for us, but for the moment we have to wait. We will see [how long it takes]."
