Henry believes that Isak's situation is unique because of his talent, which is why people are upset. Normally, when a player is performing poorly and the club wants to get rid of them, it doesn't receive much sympathy. However, in Isak's case, the club wants to keep him, and the player wants to leave.
Henry emphasizes the importance of a player attending training and being part of the team. He suggests that Isak's actions may have caused tension in the dressing room and that an apology could help to resolve the issue. Ultimately, Henry thinks it would be best for Isak to leave the club, but for that to happen, he needs to apologize and make amends.
