CAIRO: Egyptian forward Mohamed Zidan started his new adventure at Dortmund as he began training with his new teammates on Tuesday morning. A statement on the club s website announced that the 26-year old striker will wear the number 10 jersey that belonged to Mladen Petric, who moved to Hamburg in a swap deal. The report underlined that Zidan has kept a good performance under the helms of coach Jurgen Klopp. The 2008 African Nations Cup winner scored 22 goals under Klopp at Mainz. Dortmund had a successful start of their 2008/2009 campaign as they beat Bayer Leverkusen 3-2 last week-end. They will have a tough task against defending champions Bayern Munich next Saturday.
