Having gained fame in Greece as the creative playmaker for Panachaiki FC, Davourlis attracted even more attention during the 1973 season, when he helped his team become the first Greek countryside football club ever to qualify for a European competition (the 1974 UEFA Cup).
[2] Davourlis was famed for his technical ability, his ball skill, his creative passes and his powerful shot in or outside the box; furthermore, his leadership was exemplary.
After an amazing 1973 season in which he scored again 15 goals, including a hat trick in Toumba Stadium against championship contender PAOK, he achieved with Panachaiki something that no other Greek countryside club ever had done at the time: participation in a European competition, for instance the 1974 UEFA Cup.
In 1978, when Davourlis was transferred back to Panachaiki, almost nothing in Patras remained of the glorious team that fascinated Greece in the first half of the decade.
Davourlis' presence increased the level of the team, but the results remained poor, leading to the club's relegation to the Second Division in 1981 and once again in 1985.
Had Davourlis spent more years playing for a Greek powerhouse, the number of his national team selections would have been undoubtedly higher.
