Aris Thessaloniki FC
Kampantais began his professional career at Aris Thessaloniki F.C. in 2002, appearing in 11 matches in Alpha Ethniki (in 2006 renamed to Super League), scoring two goals. He remained in Salonica for another year, scoring one goal in seven appearances.
Move to AEK Athens
In the 2005–06 season, Fernando Santos proposed him to go on-loan, to gain the required experience. He agreed, and moved to Anorthosis Famagusta FC, where Temuri Ketsbaia (a former player of AEK Athens) was a player-manager. However, Kabantais returned after six months, in January 2006, after scoring only two goals and wasting numerous goal opportunities in 14 matches. Kampantais claimed that the reason Anorthosis released him due to personal problems he had with player-manager Ketsbaia which appeared to be true. He moved then to Panionios NFC for six months.
In 2006, Ilija Ivic told him that the best for him was to go on-loan again. However, Kampantais was unwilling to go, unless the new managerLlorenç Serra Ferrer would tell him so. Serra Ferrer gave him enough chances to prove his worth, but did not register him for the UEFA Champions League matches, which upset Kampantais.
Even though not considered as a first team regular, he was one of the best players in the friendly matches. Serra Ferrer trusted him in the derby vs. Panathinaikos. Kampantais, even though he did not score, played a good match.
The next matches in which Kampantais played were versus Aris and Larissa. These two matches were critical for AEK, and Kampantais managed to score in each game once (in both matches he was in the first team). Versus Kerkyra, Kampantais was awarded two clear penalties. He was announced as Most Valuable Player in that match. That was the first time Kampantais was given this award.
Since then, he appeared in every match and scored some goals. He was voted one of the two MVP in the big derby against Olympiakos in early February.
Return to Greece
Kampantais began his Beta Ethniki career in Olympiakos Volou in summer 2009. After a year, he moved to Superleague Greece, playing for OFI, and in June 2012 he signed a two-year contract with Panionios. On 10 September 2015, after a year as a free agent, he signed a year contract with Football League club Kerkyra for an undisclosed fee.
