Borussia Dortmund forward Mohamed Zidan said that a mid-table Spanish side were interested in signing him. "Out of respect for Dortmund, I will not reveal the Primera Liga team's name," Zidan told FilGoal.com on Thursday. The Egyptian international said on Wednesday he would like to stay at Dortmund, the club he joined from Hamburg SV last summer. But he still needs more first-team football as coach Jurgen Klopp usually prefers an attacking partnership of Alexander Frei and Nelson Valdez. "I aim to have a bigger role. I may consider leaving Dortmund If things remain as it is." The 27-year-old has scored five goals in the Bundesliga so far this season. Swiss striker Frei, Dortmund's top scorer with nine goals, also hinted that he may leave the six-time German champions, who lie ninth in the league table.
