Egypt's Primera Liga club lost their 3-0 win over Zamalek in the second leg of the Egyptian Premier League on Friday.
Turki Al-Sheikh Malik Pyramids, known for his impatience with the coaches, criticized Lahcen, saying his team deserved to win if it had not been for "big technical mistakes."
"Why do not we invent football? Why did not we get players involved in millions of dollars from the start," he said on Facebook after the game, "If this team were hired better, no one could stop it."
Al-Sheikh pledged to announce the new coach in the coming hours. "Today (Friday) in the evening, God willing, a great coach and international coaches clubs and teams. We have three options ready and when we settle on the right option we will contract with him."
Pyramidz, the top spender, signed Hassan in late October after resigning from Al-Borseidi's training. He was the team's third coach this season.
Pyramides suspended Zamalek's victories after they managed to exploit the numerical deficit of their rivals and drew 3-3 on Thursday.
Pyramides scored 39 points from 20 games in second place, while Zamalek increased their lead to 42 points from 17 games.
Zamalek finished the match with 10 men after Abdullah Gomaa was sent off in the 70th minute after a second yellow card.
