Apparently he's the player with the the most chances created in the league . He is only 24 btw... maybe this is the year he goes up a level and learns new tricks
Sweden has faced same poor opponents for years with Kulusevski (its even recycled ones, Estonia, Azerbaijan etc). He wasn't playing this well at all then.
Combination of new attacking coach in Jon Dahl Thomasson, and Kulusevski generally improving as a young player.
