That finish was pretty much perfect by Richarlison. Not to mention the fact that the ball couldn't have come to him any better from Palhinha's tackle. Things lined up against Raya(and us) in that sequence and sometimes there's not much you can do about it. Other than not getting caught on the ball like Zubimendi did, of course.
The goal was definitely on Zubimendi and not Raya. I'm just glad this mistake happened up 3-0. Not like against Sunderland, which resulted in us dropping two points.
