"There are no easy games at this level. It may seem easier than it could have on paper but I know the German culture: they will be a team high on discipline. An interesting couple of meetings lie ahead.
"I know all about their stadium and the atmosphere. Almost every match is a sell-out. In my first year there we were playing in the Intertoto Cup and there were 55,000-60,000 people there.
"Even if the excitement is not what we have in Turkey, there's substantial support. The Turkish community in Germany will be an advantage for us. We need to prepare well."
