What world are you living in? In your logic, he should have "forbidden" her to play for Turkey NT in OQT because they were an opponent of Dutch NT. Bahar is a married woman but she is not a slave and I'm pretty sure Guidetti won't forbid her anything
The national team is a different story because Bahar is not a decisive player there, she is not even in the starting 6 + Turkey was not the biggest rival of Holland in Anakara + Guidetti and his wife's dream was to be together in Rio 2016.. in the national team Bahar is representing her country and she has no other choice, while in the club teams she has many offers that she needs to choose one of them, the one that she think is the best for her as a player and maybe as a wife.
Just a question, a husband could not affect the decisions of his wife..?
And by the way that is not making her "slave".
