From where did you get this impression?
It's not an impression, rather information.
Alexia's transfer, depends on the relation between Vakıfbank and Galatasaray and also Vakıfbank's transfer strategy. If they sign with Kiara, then it would be a strong sign for this happening. Real Galatasaray fans love her and want her back.
Even if this happens, I would keep Cuttino, so there would be a competition and strong backup for that position. So far, I did not hear any news about Cuttino's next season. Alexia plays well with her great intelligence but still needs some improvements. The good thing for her is that, she will take more time in the team with Hernandez..
Hernandez is a good coach and he touched to all players including Cuttino, Logan, Bihter, Tashiro, Emine and even to İlkin. All improved a lot in specific areas. Definitely a strong 2nd libero is needed but if Bihter keeps on going with this improvement, she will not be the player to put aside.
Lazovic contract is until the end of this season, so if she act as a good contributer to team at the rest of the season, maybe her contract will be renewed, else a room will be kept open for foreign OH. For MB, if they keep Emine, Ayçin-Yasemin-Emine trio would be good enough. No need to touch to setters, especially to Tashiro. She is really good at settings and especially in digs. Even she tries her best in blocks. Note that, Tashiro was the 1st setter of NT and Nanami Seki was her back up, the player who was interested by Imoco.
So good foundation but still nothing is crystal clear for several positions and we can hardly wait for next developments.
That's the catch. Vakifbank may not be willing to transfer Alexia to Galatasaray but to a lower-ranked team in the league instead.
