I love Calvert-Lewin, but his injury record is a no no. There is no way Everton would sell for under £70 mil, and for that you need to be relied upon.
Toney actually looks to have a bit of vision, and his one touch passing is very good, but doesn’t seem very pacy or can create something out of nothing.
Bamford is a magnificent finisher, can link well with those around him, but has no strength and would struggle to hold the ball up.
Personally, I would buy Alvarez as a false nine, and then get Vlahovic or Toney.
Try to cover both bases and have some variation.
