Mohamed Zidan's Mainz were held to a goalless draw at close rivals Hamburg in the penultimate game of the German Bundesliga season. Zidan played for 64 minutes against his former club before making way for youngster Yunus Malli. Before their final game against Borussia Moenchengladbach next weekend, Mainz lie 13th with 39 points, three ahead of Hamburg. It is expected to be Zidan's last game with the club as his six-month loan from Borussia Dortmund finishes.
