I'm afraid Eczacıbaşı is in danger zone. Both THY and Galatarasaray are peaking and can get surprise wins against Vakif, Eczaci and Fener.
Right now both THY and Galatasaray have 5 loses, Eczaci 3.
If everthing goes as expected THY will end up with 7 loses, GS with 8 loses and Eczaci with 4 or 5 loses.
But THY or GS's possible win over Eczaci can change everything.
THY will play against Fener, Eczaci, Nilüfer and Yeşilyurt. If they win 3 of these matches ,I think they will be in.
GS will play against Vakif, Fener, Eczaci and Nilüfer. They need to win at least 2 of these matches ( especially against Eczaci)
Eczaci will play against Vakif, Fener, THY and GS. If the lose both of them , they will be out.
