Rapid București

Lazăr joined Rapid București in the summer of 2006. In March 2009, he was involved in an incident in which he was judged to have been fouled in the box by Oţelul's Alexandru Bourceanu. Lazăr, adamant that it was a fair tackle, refused to take the penalty and eventually persuaded the referee to award a drop ball, which his teammate Ovidiu Herea then kicked out for a goal kick.

PAOK

On 21 July 2011, Lazăr signed a three-year contract with PAOK FC after he was chosen by the club coach László Bölöni. He quickly became a key player for the club even after 5 matches. On 25 March, in a game against Kerkyra, Lazăr scored two goals, to help his team to a 4–0 victory. On 6 January 2013 Costin Lazar scored a wonderful goal for PAOK, winning 4–1 away to Panthrakikos, in a match of the Super League Greece. This goal voted as the best of the week.
