Marius Grigonis, CSKA guard:
We were following Grigonis for last years, he was on our radar. We believe that we bring here the player that can play multiple positions, especially on the perimeter at 2 and 3. He has the size, knowledge, creativity and execution that matches the level of our team. We are thrilled to have him here, we welcome Marius on great family of CSKA. We wish him to stay healthy and win many games and trophies with our team.
I'm really excited to be part of CSKA. CSKA has been one of the best organizations over the years and has won many championships, so as an athlete, to be able to play for this club is a big achievement for me. I'm looking forward to meeting the CSKA family and showing what I am capable of.
