The Dervishes lost a chance to win their fourth ever title after they succumbed to a 1-0 loss in Alexandria thanks to a Flavio Amado first-half header.
Al-Agouz was seen furious at the referee following the game, as the former Ismaili star tried to get on the pitch to confront the Spanish judge.
"He is the worst referee I've ever seen," Al-Agouz said after the game.
"Many of his calls slowed down the game's pace and this affected our players' tempo.
"We are really disappointed that Egyptian FA officials didn’t show us enough respect when they brought a mediocre official for a league decider."
Honoured
Despite the loss, Al-Agouz confirmed that he is honoured that his players managed to take the league title to the wire.
"We congratulated all our players after the game. They have earned everybody's respect with their displays and results this season.
"We are really proud that we built a strong and young team that can play at the top level for years to come," Al-Agouz concluded.
