It's going to be an important season for Czech NT this year and I'd like to share some information about opinions here. There are a lot of talented players but they haven't shined yet...Havelkova and Havlikckova are the most well known players from Czech republic indeed.
I guess the roster this year should be almost the same as last year.
Setter : Lucie Muhlsteinova, Pavla Vincourova
Opp : Aneta Havlickova, Tereza Vanzurova
MB : Kristyna Pastulova, Michaela Monzoni, Nikol Sajdova, Ivona Svobodnikova
OH : Helena Havelkova, Sarka Barborkova, Martina Utla, Karolina Bednarova, Andrea Kossanyiova
L : Julie Jasova
Not sure about Ivana Plutchova and Tereza Rossi if they can be added. I like Martina Utla quite a lot. Obviously she's not a world-class OH, but can help the team with Havelkova in that position.
