Let's face it, nothing will be the same after Zhu leaves, especially since Lonneke is also certainly going. Doesn't matter who Vakif brings, the team is guaranteed to be weaker in 2019/2020 than in the last 2 years. There will be NO sweeping competitions. The only question is by how much.
If both Boskovic and KYK remain in ECZ for the next year, there are 2 options:
1)Quite a lot, but it can still potentially "steal" one of 2 domestic competitions (I don't count Supercup)
2)Extremely so, no chance for any trophy
If, for the sake of going for the option #1, he gambles with the future of Turkish NT (as seems possible, and indeed, likely, given Haak's signing), he will have sent a clear and unambiguous signal that, of the 2 jobs he has, he prefers his club gig, and for that, he would deserve to get fired from the NT (presumably the money the Federation pays him is no less "green", as the saying goes).
Not that he will be, even if Turkey does nothing in the next few years, but that's a topic for another day.
