Pathiakakis started his football career in Apollon Athens, where he played from 1971 to 1977. He then played for one year in PAOK and in 1978 he was transferred to Nea Smyrni, in Panionios.

In 1994 he sat on the bench Apollon Athens and associated his name with the most successful period in the club's history. Under his guidance, Apollon created a young team with excellent footballers who, with the help of some experienced players, play quality football. Demis Nikolaidis, Theofilos Karasavvidis, Bledar Kola and the older ones Antonis Minou, Frank Klopas, Tasos Mitropoulos give personality to the team. In his first season, he led them to 4th place and earned a place to the UEFA Cup of the following year, while in 1996 he reached the Cup final of the , where he was defeated 7–1 by AEK Athens.^[5]

In the end of the season he won the Cup beating Ionikos by 3–0.^[6] and the following season, he led the club to the round of 16 of the UEFA Cup excluding Bayer Leverkusen. However, the elimination in the Cup by Olympiacos with the embarrassing 6–1 led to his dismissal.^[7]

He was sidelined for a year until February 2002 when he was re-hired by Akratitos. But before he could really take over, he died during training of a heart attack.

Pathiakakis died of a heart attack five days after his return to Akratitos. He cooled down at the Ano Liosion stadium during training on February 8, 2002 at the age of 49. Four years earlier he had suffered another heart attack at the same stadium and had undergone a double bypass, but despite doctors' advice to avoid excitement, he chose to continue "living dangerously" as a coach. At the same time, he did not stop smoking.^[8]

Everything happened so fast that no one had time to react. The training session was almost over and Pathiakakis was playing a bet with goalkeeper Gintaras Staučė, shooting him from outside the area. He had won the first game and when the Lithuanian goalkeeper asked for a rematch, the coach suddenly fell down. They rushed to him for first aid but the fatality soon occurred before the ambulance arrived. At the hospital, he was pronounced dead from an acute myocardial infarction.
