BC Triumph have appointed Lithuanian Valdemaras Chomicius as their new coach.
The 51-year-old, who coached Unics Kazan this season, turned down a chance to remain at that club.
He will instead attempt to lead Triumph into the EuroChallenge.
On Thursday, they were drawn against Lugano Basket in the Qualifying Round for the EuroChallenge.
"I'm very happy to become a part of Triumph club," he said.
"I got some offers from European clubs (Zalgiris, VEF Riga) during the (Russian Superleague) play-offs, but my mind was only about UNICS.
"I had the chance to stay on the UNICS coaching staff, but I was very interested in BC Triumph's offer and signed the contract with the team from Lyubertsy.
"My signing is a step forward, a new challenge for me.
"Triumph's roster will be composed of young and talented Russian players, and I like to work with the young. They work hard, play and practice with all their heart.
"They have a good future."
Chomicius has also worked as the head coach of Ural Great and Dynamo Moscow.
He will be an assistant coach this summer to Kestutis Kemzura with Lithuania's national team.
Chomicius was a member of the Soviet Union national team from 1979 to '89.
Following its break-up, he played for Lithuania and served as captain from 1992 to '95.
