Pulisic is their most talented player but the injuries would worry me. He hasn’t quite looked the same player this season.
As for Haaland, Werner plus cash would work for Chelsea and Dortmund. Chelsea get a much better player, Dortmund get a striker who can score in the BL and some cash.
I don’t know why Haaland would go there though, he’ll have a number of better clubs after his signature.
