Antonis Nikopolidis (; born 14 January 1971) is a Greek professional football manager and former player, who is the current manager of Super League 2 club Proodeftiki. He is regarded among the best Greek goalkeepers of all time having been awarded the most caps in the Greece national team and playing an integral part in the UEFA Euro 2004 triumph. Club career Anagennisi Arta Nikopolidis made his first steps at his local team of Anagennisi Arta, from which he was transferred to Panathinaikos in the summer of 1989. Panathinaikos He made his debut during the 1990–91 season in a match against his future club, Olympiacos. In his first years as a Panathinaikos player he was a back-up for Józef Wandzik. In 1995, he played five games as Panathinaikos won the championship and three as they retained it the following year. However, it wasn't until the 1997–98 season that he established himself as a regular goalkeeper at the age of 26. In the 2002 Champions league, he helped the club reach the quarter-finals but, in the 2003–04 season, he lost his place to Konstantinos Chalkias when his contract negotiations broke down. Panathinaikos offered him €400K per year which, although a pay-rise, he thought was not in line with his contributions to the team over the past 15 years nor with his current market value. As he did not immediately accept the offer the management became suspicious and decided to relegate him to the bench for the rest of the 2003–04 season. The Greek sports media and Panathinaikos fans at first took his side in the conflict and criticised president Vardinogiannis. Just before UEFA Euro 2004, rumours were circulating that Nikopolidis had been approached by arch-rivals Olympiacos. It was discovered later that he had signed an agreement just before the tournament begun earning him €600K per year for three years. After that, the fans' disappointment in him was displayed during the celebrations following the team's 2003–04 season double when Nikopolidis, while raising the trophy, was booed by the majority of the crowd. Olympiacos Soon after being instrumental in UEFA Euro 2004 helping Greece to lift the trophy, Nikopolidis joined Olympiacos, making an immediate impact for his once rival team. Keeping a clean sheet in the first derby against his former club in the process, he went on to win two Doubles in a row, making him the only Greek player to win
