Shtalenkov began his major-league hockey career with Dynamo Moscow in 1986, backing up veteran star Vladimir Myshkin. The team won the Soviet Championship in 1990, ending the 13-year dominance of rival team CSKA Moscow, with Shtalenkov and Myshkin splitting playing time almost evenly. Dynamo went on to win the championship the next two years in 1991 and 1992, with Shtalenkov entrenched as the starter. By the 1991–92 season, he was also the starting goaltender on the Soviet national team. Shtalenkov moved to North America in 1992, after backstopping the Unified Team to the Olympic gold medal, signing with Milwaukee Admirals of the International Hockey League. After one season, he was drafted 108th overall by the Mighty Ducks of Anaheim in 1993 and spent five seasons with the team. He originally began with the IHL's San Diego Gulls, but received the call-up to the Mighty Ducks after Ron Tugnutt was traded to the Montreal Canadiens and Shtalenkov served as back-up to Guy Hebert and would continue to do so until the 1997-98 season. During the 1997 Play Offs against Detroit he took over for Guy Hebert who suffered a knee injury in Game 2 and performed very well forcing the Red Wings into overtime in every game, facing 162 shots in the series. In Game 4 he registered 70 saves in a double overtime loss. Under new head coachPierre Page he saw more ice time and became their starting goalie in 97/98 on March 8, 1998 after Guy Hebert suffered a severe shoulder injury forcing him to miss the remainder of the season. He appeared in 18 of the last 21 games playing a career-high 40 games. Shtalenkov was claimed in the 1998 NHL Expansion Draft by the Nashville Predators but was later traded to the Edmonton Oilers in exchange for Eric Fichaud. In his one season with the Oilers, he shared the starting goaltender role with Bob Essensa, but was acquired by the Phoenix Coyotes at the end of the season and served as Nikolai Khabibulin's back up. After only a handful of games in Phoenix in late 1999, Shtalenkov was traded once more to the Florida Panthers for Sean Burke. In 2000, Shtalenkov returned to Dynamo Moscow and eventually retired from hockey in 2002.
International play
Shtalenkov excelled internationally over his career in which he represented the Soviet Union, the Unified Team and Russia many times in the World Championships, Canada Cup, World Cup of Hockey and Winter Olympics. He also played in the 1991 Super Series for Dynamo Moscow versus various NHL teams. At the 1991 Canada Cup, while playing on a team that was missing most of its elite stars, he still managed to hold an undefeated Canada to a 3-3 tie in their last game. At the 1992 Winter Olympics he won a gold medal with the Unified Team as the starting goaltender. He was the 3rd Goalie at the 1996 World Cup of Hockey for Russia, though he did play against Germany in one of Russia's Exhibition games in which they won 4-2 in Landshut, Germany. On a team that was missing many of their top stars due to players declining and injuries, Shtalenkov carried the team to a silver medal with Russia with 4 wins in 5 games in the 1998 Winter Olympics in Nagano, Japan.
Personal life
On March 27, 2012, Shtalenkov went missing after arriving to Moscow on a flight from Magnitogorsk two days earlier. Shtalenkov's wife phoned the police after her husband did not come home from Moscow's Vnukovo Airport on Sunday and reported him missing. However, after being informed of the reports of his disappearance, Shtalenkov phoned his wife and informed her of his well being, according to police sources.
