You can't adjudge a team or rate a team by their performance in a preseason tour because such matches are not played with utmost seriousness as a result of their importance, nevertheless the Leverkusen side are far more sophisticated and well equipped in terms of player ratings and perhaps this is a major factor that could also determine the outcome or the result of the match.
Very ture and correct, most pre season games are not even played with the teams actual starting 11 because they would not want to risk certain players in a preseason tour and end up not having him to be able to play during the actual season when he will be needed the most so results gotten from such games are not one with which you will use to judge the team because you may be actually wrong trying to do that.
