What is so repulsive about the idea of Calvert-Lewin being our centre forward?
Yeah, his numbers are boosted some by sub effects, but he has a better goals/minutes ratio than everyone at the club not named Richarlison (and it's close between the two of them) for a side that provides next to nothing in terms of service to its strikers. And that's giving Gylfi credit for penalties, which he doesn't really deserve because anyone can score a penalty (Calvert-Lewin included).
Unless someone with obvious quality (and value beyond the next year or two) becomes available for a good price, we don't need to bother adding a CF. We can just develop the guy we already have, who's actually pretty good and could get much better.
What we really need is a midfield. I'd entertain short-term options in that position because the balance in there is totally fucked and it's really holding us back.
