Kostas Giannoulis

Konstantinos Nikolaos Giannoulis (Greek: Κωνσταντίνος Νικόλαος Γιαννούλης; born 9 December 1987) is a Greek footballer who currently plays for Greek Superleague club Asteras Tripoli as a left-back.

Panionios

He started his professional career in 2005 with Panionios, but he failed to make a single appearance for the club, and he was loaned to Fostiras and Pierikos. He made 25 appearances for Pierikos in their successful Gamma Ethniki campaign, where they won the title and promotion to Beta Ethniki.

Iraklis

Köln

In May 2010 he signed for Bundesliga side 1. FC Köln. Koeln have been quick to indicate their contentment with this deal. "We are very glad to have signed Konstantinos Giannoulis, who will be a gain for the defence," said general manager Michael Meier to the club’s official website. "He fits exactly our left back requirements for the coming season." Kicker reports that because of Iraklis ongoing financial difficulties, Koeln have been able to swoop for the defender by tabling a “low six-figure fee”. They were not the only German outfit interested in the full-back, as Kaiserslautern had already made concrete steps towards securing the Greek’s signature. After half a season however, having never played for the first team, he was told that he could leave the club for free.
