[4] Saravakos started his professional career at Panionios where, at the age of 16, on 26 December 1977, he made his debut in the championship against Egaleo.
[6] During the 1981–82 season, Saravakos had the most productive year in the club as he scored 13 goals in the league, while his performances also made him an international.

[27][28] Facing Olympiacos again, the duo of Saravakos-Dimopoulos was successful again as with their 2 goals, Panathinaikos claimed the title on penalties, where they won 4–3.
[29] In June 1988 the then president of Olympiacos, George Koskotas, offered Saravakos the "unrealistic" amount for the Greek data of 600 million drachmas,[30] but failed to dress the athlete in the red and white shirt.
[32] In the summer of 1989, Panathinaikos acquired the striker Krzysztof Warzycha,[33] who connected perfectly with Saravakos and the two of them led the club to the championship in 1990.
On February 25, 1990, Saravakos played for the third time in his career in a match where Panathinaikos scored 4 goals against Olympiacos, winning 3–4 in the Karaiskakis Stadium, with him as the captain.

At the end of the year, AEK, respecting his contribution to the club, released him by terminating his contract by mutual consent.
[60] In the summer of 1997 after a year of absence from football [61] Saravakos returned to Panathinaikos to end his career in his favorite club.
He was part of the team that claimed qualification for the UEFA Euro 1988 and contributed to the great success of qualifying for the 1994 FIFA World Cup in the United States.
[64][65] He possessed excellent technical training and footballing intelligence, with a strong emphasis on finishing, game development and a keen ability to score goals, being regarded as one of the most effective takers in all foul and penalty kicks.
