Point is, if Amrabat is valued at ~30m, you instead do Lavia for ~50m. Don't have the extra ~20m? Throw McFred at the problem, or until you can get the extra for Lavia.
Yup, you said it best. But why not go for Lavia for ~$20m more (allegedly what the valuation difference would amount to)?
I have nothing against Amrabat, and maybe he is just the type of skill set and mentality we need most at the moment, but appears to me buying C+/B- prospects when you can go for A prospects, that are younger and with better resale value for $20m more (over the life of the contract), is a better approach in the long term ambitions.
Of course this is all moot if that’s who the manager has identified for his project.
