Mainz GM Christian Heidel admitted that Gamal Hamza is taking a long time to settle in with the Bundesliga club. "Hamza's progress with the team is so slow. We have paid 25,000 Euros for his services," Heidel was quoted by Bild. Hamza has yet to play a league game in Mainz's colors since joining in the summer after his contract with Zamalek expired. The Egyptian forward recently admitted that his situation at Mainz is not good as he needs to play games for Tomas Tuchel's side.
