I hope Richarlison scores 20 goals for us, but if you want to know why I want him to move on, it's in the bolded text. Some people just have bad luck, and their bodies fail them. Don't know why, maybe it's his training regimen, decision making, or maybe it's just bad fucking luck. Either way, he has a history.
His body language on the pitch is not great when he's not on one of his hot streaks. He'll be great for the early FA Cup rounds in January and some of the Europa league matches, but to think that he's going to see the kind of minutes they had hoped from him going into last year as Kane's replacement is a little unrealistic. So he's going to be sitting for stretches behind Solanke, Kulu, Son, BJ, Werner, and Solomon. He might not want to leave the EPL, but the time is coming where he'll be forced to move to Serie A or Ligue 1, or to a lesser side in the EPL like a Fulham.
Solanke was wanted by Ange, so there's that. I think he'll be fine, even though he's a little one dimensional. I'm excited to see Son play more of his natural wide position.
