I didn't even know he existed until this season. He came up through a lower division Swedish club and then moved to Atalanta in his teens. Was a complete surprise to see him getting called up for Sweden.
I think he almost looks too good to be true. He and Milinkovic-Savic seem to represent a kind of footballer that used to be common in the late 90s but is a rare breed nowadays with their physicality and high skill level. I can't wait to see what he'll do with 50 starts under his belt.
I just mentioned this in the transfer section, but I'm surprised that Atalanta sold him so early for a relatively standard fee. Adding him to their squad in the summer could have practically guaranteed Champions League qualification again in 20/21.
