Anyone who is not included in the main roster can say that there is a problem in the team then. Neriman is not the first and not the last player to experience this. Sıla and melis also got cut and did no such thing.
Even Orge did not make such stupid thins when everyone knows she has a beef with Guidetti.
Melis and Sila's situations are not like Neriman's. They are probably just happy to be in the wider roster, they are not established player like Neriman who already represented NT many times. It would only be comparable, if Naz would be invited to NT now and she agrees to play but all of a sudden Santarelli would decide not to let her play at all. Then, this would be comparable to Neriman's case.
Neriman said multiple times that she was healthy, ready and willing to play for NT but Gui excommunicated her once she was not in a good place to play (divorce could take a toll on people, look at Smarzek for instance) many top players asked to be excused from NT once in a while and they are welcomed back to NT (e.g. ognjenovic) Neriman's case was very comparable to stevanovic indeed. That's why she probably hoped that things would change when Santarelli was appointed as head coach. I cannot imagine the disappointment she had after this. Poor girl😩
