Unfortunately he will sticky with her until Tokyo.... good thing that you guys think the ECH is such a big deal because that is the only tournament Serbia might have a chance in winning ......This floppy game they are running won`t get them anywhere.
Remember when Terzic said during the WCH qualification tournament that he wanted to win it quickly and the way to do was to ride with Boskovic??? so yeah even against those super weak teams they would only set her....and here were are 2 years later and nothing has changed yet. 
This elimination is absolutely embarrassing. 
If Serbia still stick with Zivkovic until Tokyo. I'm not sure if Serbia would even qualify for the OG. Maybe I'm wrong, but looking at her performances on the court, she just doesn't seem like a highly motivated person to me. After all these matches in the preliminary round, her connections are still terrible. Rasic could rarely hit the balls hard...and she still hasn't improved the quality of her sets...I'm curious to know how Terzic train the setters.....
Boskovic seems to have more down times this year, making lots of errors especially during crucial points. It reminds me of her rookie days. She needs to find ways to control her nerves and play smarter . I can't fully blamed her though looking at the terrible balls set to her 
I hope Terzic will make some tactical changes after VNL. WIth Boskovic/Mihajlovic have already been well-studied by other teams, you need a plan B or C to win the games. (I won't get my hopes up the changes though) They need to work on their defence, reception and passing, like I have always said. They are probably the weakest in all these elements among the top tier teams.
