In the early 1970s Gounaris became known for his plowing runs down the whole right wing, transitioning defence into offence. His partnership with PAOK's left fullback Kostas Iosifidis became formidable not only for PAOK, but for the Greece national team as well. The two backs played a vital role in the team that won PAOK its first ever championship. The duo would go on to play in seven cup finals for PAOK, from 1970 through to 1978. Although Iosifidis decided to remain at PAOK for the duration of his career, Gounaris transferred to PAOK's most fierce rival Olympiacos, once his twelve-year contract expired. PAOK's fans never forgave him for what they saw as betrayal, but his fatal crosses and unceasing runs down the flank ensured that he would always be part of the club's history.
After his retirement as a football player, he went on to manage PAOK in the 1990s, as well as having a very brief tenure with Olympiacos He end his career with Makedonikos in 1987.
