Only on Wednesday was I able to ride a bike again. This injury came at a terrible time, I was just getting in form. Now I have had to stop for three weeks. 'The problem was I started to train again after the Shakhtar match too soon; that was a mistake. There are many important matches coming and I hope I can help the team.' 'I have no chance [of playing against Dortmund],' he added. 'I can't even run. I tried last week and was in pain immediately. This situation is difficult, but I have to be at 100 per cent first.

The important thing is to start running again without pain. Only then am I able to work with more intensity and work with the team again. I need time, but we don't have it. I must be patient. 'We have two big matches ahead of us. Dortmund know how to win against us and the cup match in Leverkusen is even more important. Two good results would be good heading into the Champions League. We need to have confidence and we must not underestimate Porto.'
