He was never boss and I guess he's learned a lot from the previous managers' mistakes. He will get a trial period so let's hope that he can get everyone motivated, and most importantly, gain some points!
You could be right but some players have that goal scoring quality where they know where the goal is by instinct. Richarlison will provide great attacking options as well as defence duties from midfield. Not a clinical striker in my eyes. Well, maybe not yet.
