I think she could be a good duo with Lukasik. How is Medrzyk recent shape? She is normally a better receiver than Saliha so she could be a good sub to her
IMO Medrzyk will just be a sub player for reception, the real question is if its going to be Saliha or Fedusio in the starting 6. In the NT Fedusio was rather bad so far, however she always has good club seasons and ends up being one of the best OHs of the league, but still, I think Sahin will be starting with Lukasik in the beginning of the season and Fedusio may take her place if she doesnt perform well, but hopefully she does.
