Of course, friendly matches will never tell the whole truth about what awaits us in the regular season. However, I think it will not be easy for Bayern to fill the gap that arose after the leaving of Robert Lewandowski. In today's game against Manchester City you could see the difference. Hopefully Sane will soon begin to get understand better with the other players in the club and the team play will look better, but if they don't raise the level then Dortmund may finally have a chance to fight for the Bundesliga title.
