He then transferred to Panathinaikos where he developed excellent skills as a libero defender, becoming an essential member of the brilliant team that conquered 1995 and 1996 Greek league championships. During this last period, the "Green Shamrocks" reached the semi-finals of the UEFA Champions League.
Ouzounidis' international career comprises fifty games with the "Ethniki", and was even the team captain during Vassilis Daniil management, making a remarkable couple with Nikos Dabizas, before Traianos Dellas' appearance.
When he finished his career as a football player, Ouzounidis managed the team of Kappadokes Alexandoupolis (4th division) as head coach. Later, in the 2005–2006 season, he served as an assistant manager in Xanthi. In May 2006 he became the manager at APOEL. His first season was a very good one finishing first and winning the Championship 3 games before the end of the season. His team also reached the semi-finals of the Cypriot Cup. He resigned from APOEL during the second season, after four draws and three defeats in the first 15 games.
He accepted an offer from Larissa on 9 May 2008. In his first season at Larissa he was very successful driving the team in to the playoffs and securing a spot in the next Europa League. His record in the first year seemed to confirm Larissa chairman Piladakis' idea on using young Greek coaches to lead the team to success. Unfortunately his second year at Larissa began badly as the team was knocked out in the first qualifying round of the Europa League and on 22 February 2010 the young coach was sacked due to the fact that Larissa had found themselves just above the relegation zone. On August 9, Ouzounidis signed a contract with Iraklis. On 31 January 2011, with the club being only three points above relegation he resigned from his position as manager. He signed with his first team Skoda Xanthi at summer 2011.
