However, Krul still thinks that the transfer was a good deal for Newcastle, and the club has the money to sign top players to replace Isak. He also notes that the current generation of players is different from his own, and he wouldn't have liked to see Isak behave in the same way.

Krul believes in the importance of treating people with respect, and he thinks that Isak's behavior was not respectful to his former teammates. He also mentions Mark Guehi as a positive example of a player who has handled a similar situation well.

Krul's comments suggest that he thinks Isak will face consequences for his actions, and that he believes in the idea of karma.
