Borussia Dortmund forward Mohamed Zidan is 90% out of the weekend's game with Bayer Leverkusen due to an ankle injury. Dortmund's official site quoted manager Jurgen Klopp as saying that the Egyptian, along with striker Lucas Barrios, is not fit for the Bundesliga clash. "We are not sure whether Lucas will return today. Mo(Zidan) is 90 per cent ruled out," said Klopp on Wednesday. Zidan and Barrios sustained minor injuries in the recent 2-0 win over Bochum. The Egypt forward played well for Jurgen Klopp's side last weekend as he filled in the void left by the inured Tamas Hajnal in midfield. He is pushing for a return to the Egypt squad, ahead of next month's crunch qualifier with Algeria.
