Zamalek coach Helmi Toulan says the trip to Congo's Leopards is the most difficult in his career, while several players have suffered from minor illness. The Whites prepare to take on the Dolisie-based club in the Champions League group stage on Sunday as they had to endure a long journey to the home city of their hosts. "This is the toughest trip I ever had. We endured nearly 20 hours of travelling and after we arrived, the hotel was so poor that we had to move," Zamalek boss Toulan told the club's website. The club said they had finally arrived to the city of Dolisie following hours of ‘suffering'. Team doctor Mostafa Al-Monayeri had to deal with several vomiting cases during the internal trip to the venue that will host the game. Although they will play during the fasting hours of Ramadan, Zamalek players are allowed to break their fast on Sunday evening.
