Early career, Panionios Patron and Panachaiki 1962–1971 Davourlis was born in
Patras. Having been discovered by Panachaiki former player and scouter Spyros Voulgarakis, he began his playing career at the age of fourteen with a
Panchaiki subsidiary team, Panionios Patron. Two years later he joined the senior team and contributed to Panachaiki's battle to reach the
Greek first division. His most notable achievement at that time was that he became the first Greek football player to be selected for the national team while playing for a second division team. Finally, after several unsuccessful attempts, Panachaiki made it to the "big" division in 1969 and Davourlis' talent shone. However, the team was involved in a bribery scandal and sunk again to the lower division. Fortunately enough for Davourlis, they were back a year later and the
Black Prince of Patras led Panachaiki's rise towards glory.
Panachaiki and Olympiacos 1971–1978 In the 1972 season, Davourlis scored 15 goals and Panachaiki finished sixth. The best was still to come though. 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. Nevertheless, his heart was travelling somewhere else.
Panachaiki 1978–1985 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. He ended his career with
Korinthos in 1986. Later on he worked for Panachaiki as a scouter discovering many talents until the year he died, the most famous of whom is
Grigoris Georgatos. ==International career==
