I think Bartsch will only play in CL and in the case Gabi doesn't perform well. I doubt that Ebrar will lose her starting position
I think so too. Gabi has been parcticing with team from the beginning of the season so she would be the first used ones and MBH would be used when Gabi is not doing well.
I think MBH is for CL because Gui felt some walls between their team and imoco. Imoco is so strong so far. With MBH, they would be much more competitive compared to now.
Gabi-MBH-Haak-Maja-Rasic-Zehra lines would be enough to compete with imoco. I think vakif is the only team who can resist against imoco in champions league.
