Isak doesn't strike me as a player that is overly greedy about his salary, I'm more worried about the fact that he was in Real sociedad before us that was in a similar situation table wise. You'd think he'll get tired at some point at being in teams below the best teams rather than just being in the best teams.
But hopefully we get CL and do better in the new format which should suit us better. While its a big ask, especially for someone from Sweden that doesn't have a local connection, I'd hope he stays and becomes a legend.
