Career
Pavlenko started his career at the age of 14 in the youth academy of Dynamo Moscow before moving on to Academica Moscow and then the youth squad of Football Club Lausanne-Sport in Switzerland. In 2001, at the age of 16, he signed with Spartak Moscow and made his first team debut the same year. In 2002, he became a first team regular gaining his first opportunity to play in the Union of European Football Associations Champions League.
He lost his regular place in the lineup in 2005 after injuries limited his playing time and consequently was loaned to Shinnik in 2007.
After that, he has returned to Spartak and got back in the starting XI. He managed to beat a long standing Spartak midfielder Egor Titov for the starting playmaker position at the start of 2008 season. However in July Pavlenko was hospitalized with unspecified bladder problem.
In March 2010 he was loaned until the end of the year to Football Club Rostov.
