Speaking at a post-match press conference, Nikolaidis was quoted by Sportnet as he announced his resignation after a negative reaction from the home fans in the wake of the victory.
“I wasn’t expecting those reactions from the crowd.” Nikolaidis said.
“I don’t want to be the president of a club where the fans demonstrate against the team.
“This is my last day as the president of AEK.
“I don’t have anything else to offer to the club.
“My decision is final.”
Earlier this year, Nikolaidis had announced his decision to leave the club in May of 2009.
