Galiamin was born in
Moscow. He started playing with hometown's
CSKA Moscow, being an automatic first-choice from his second season onwards and helping the team to
the double in his final year, 1991. Aged 28, Galiamin moved abroad, signing with
Spanish club
Espanyol, managing to appear sparingly during two
La Liga seasons and being relegated in
his second – he became a starter in
1993–94, helping the
Catalans immediately return to the top level. In the 1995 summer, due to constant injuries, Galiamin retired from the game at 32, after
one season with
Mérida (Spain,
second level). In the following decade, already back in his country, he took up coaching, starting with
Dynamo St. Petersburg then successively managing
Kristall Smolensk,
Khimki,
Tom Tomsk,
Anzhi Makhachkala,
Spartak Nizhny Novgorod and UOR Master-Saturn Yegoryevsk; in 2002, he served as Saint Petersburg's
director of football, occupying that position six years later at
FC Saturn Moscow Oblast. ==International career==
