Just as I wrote it today, there is a rumour of Gaila to Eczacibasi. I have nothing more to say other than Ferhat has no clue of what he is doing, he is panicking and just transferring whoever he can. Almost sure he will drown in that chaos and will be kicked mid season.
Derya is a bad receiver and nowhere to be compared to Hande/Meliha. Tugba can be compared to them considering she is a better receiver. Derya is like Neriman, but a younger version of her at the moment, I hope she will improve her receiving skills. From what I understood, Giovanni does not consider her in Vakifbank, Tugba got more chances than her although Tugba will leave. Besides that, if rumours of Pietrini/Nika to Vakifbank is correct, then they will have 3 foreign OHs and Derya will be 4th option.
I like what FB does and they are probably the only team that can challenge Vakifbank next season, with a way smaller budget than Vakifbank. On the other side, Vakifbank's budget is becoming annoying and difficult to compete.
Derya should leave somewhere and play as starter... Hande was very bad at reception as well and was an MB/Opp earlier in her career but she played regularly in GS, EczV, NT etc and improved.
Kim Yeon Koung even said her reception was bad when she was young and it was just the experience and training as hard as possible that made her improve.
Yes a few seasons of training with the best coaches does wonders but you can't expect to improve under the same conditions, you have to challenge yourself and play as much as possible.
