Zamalek chairman Mamdouh Abbas justified his decision to keep Reiner Hollmann in charge of the team by referring to the stability Arsenal and Manchester United enjoy. German tactician Hollmann has come in for fierce criticism following Zamalek's disappointing results on the local and continental stages. The White Knights bowed out of the CAF Champions League after finishing bottom of Group A. Zamalek also made an indifferent start to their Egyptian League campaign, losing twice in the first eight games. Nevertheless, Zamalek board opted to keep faith in Hollmann, who took over in the summer following the resignation of Ruud Krol. They just replaced assistant manager Tarek Yehia by Zamalek's former left-back Ahmed Ramzi. Abbas believes the board made the right decision. “During a short spell, Zamalek changed seven coaches, something which is not acceptable for any club in the world,” he told the club's official website on Friday. “People should look at Arsenal and Manchester United, who work with same managers they had many years ago even though they do not won trophies every season.” United's manager Alex Ferguson has been in charge of the Red Devils since 1986 while Frenchman Arsene Wenger was appointed as Arsenal coach in 1996. League Dream Abbas refused to rule Zamalek out of the Egyptian League title race. Zamalek's arch-rivals Ahli are firm favorites to win the league title for the fifth consecutive season. If Ahli won their rescheduled games, they would have a three-point lead over their traditional competitors. “The fans shouldn't have that disappointing tone. The club are determined to compete for the title until the very end.” “We will continue to strengthen Zamalek's squad, but the current crop of players must be aware there will be no room for leniency. “Any players who doesn't want to play here then he should leave,” Abbas added. Eleven-time league winners Zamalek have failed to win Egypt's premier competition since 2004.
