In 1956, he went to Greece to coach Olympiacos. The team won the double in the 1956–57 season. The league was won after a long run which ended with Olympiacos winning a play-off match against eternal rivals Panathinaikos in the neutral Nikos Goumas Stadium (1–0). In the cup, Olympiacos beat AEK Athens 1–0 in the quarter-finals with a goal by Babis Kotridis, and once again Panathinaikos (1–0) in the semi-finals. The team concluded by winning Iraklis 2–0 in the final and celebrated the first of three consecutive doubles (1957, 1958, 1959) that still remains a record for Greek teams.
