Korneev started his
club career with
Dynamo Moscow, but he eventually moved to
CSKA Moscow, where he became one of the club's cornerstones in the 1960s. While a member of the Red Army club, Korneev won a
EuroLeague championship in
1963. He scored 15 crucial points in the tie-breaking
final game against
Real Madrid, after first two games of the finals were not enough to crown a champion. He made it to the EuroLeague Final once again, two years later, when Real took their revenge for what had been a bitter loss 2 years earlier. In addition to that, Korneev helped CSKA to win five
Soviet Union League championships. Korneev left
CSKA in the prime of his career, due to a
Soviet rule at the time, that did not allow players above 25 years old to play for the Army-supported team. ==National team career==
