I don't think he should stay past the summer. Is best if he leaves this summer with on high as I have a feeling he would do a good job in this spell again. I'm already seeing some improvement in the way we play, let that continue and in the new season appoint a new manager that would continue the work. Because at his age I don't think he has it to go another full season. And it's best to walk away when you done a good time then leave in shambles like Mourinho did. At least if Hiddink finish on a positive note this summer he would have that as a great memory. Because he has been one hella of a coach, and to have left into retirement the way he did with Netherlands was not pleasing.
