[1] He had trained at Levski Sofia's Youth Academy as a young player.
Between 2006 and 2008, Yashar played Kaliakra Kavarna for two years before he eventually joined Levski Sofia.
He made his unofficial debut for Levski on 5 July 2008 in a friendly match against Spartak Pleven.
However, Yashar who was brought to Levski Sofia by Velislav Vutsov, did not fit new manager Emil Velev's vision for the team.
However, the transfer didn't materialize, so Yashar was loaned out to his ex-team PFC Kaliakra Kavarna for six months, where he was capped 12 times and scored 4 goals.
