I agree with you, but when I see that FB fans don`t want her to stay, I want that she left this club, but it`s only my opinion so everybody can have difficult opinion about it
Edit: I didn't see vyz's reply before posting, sorry for redundancy.
I think there are two reasons why you feel like Fenerbahce fans don't want Kasia.
1) Some fans (me included) thought Fenerbahce didn't need Kasia, at the beginning of the season. The reason for that is mainly the 3 foreign player rules and having Seda and Sokolova, who are more than decent opposites, on the roster. Kasia is a very good player, deserves to be praised. No doubt about that. But I would personally prefer Fenerbahce to play with Fürst + Seda than Kasia + Ergül / İpek / Çiğgem (in turkish league of course).
Also thinking that Fenerbahce could have signed a world class receiver with the money which was sent her way, didn't really sank well with some.
So basically for some fans it's really nothing personal against Kasia. We just felt it wasn't the right decision.
2) Some fans (who basically started to be interested in volleyball, after last years success) are disappointed with her simply because she failed to fill the shoes of her predecessor. Oblivious to the fact that it's very unfair for any player to be expected to fill Gamovas shoes.
Yet most of the fans (including the ones who didn't want her in the first place) still support her.
