Bayern Munich, in this match, is more effective nd could really maximize their chance to score the game. Although Barcelona's ball possession was higher, in fact, that didn't guarantee to score. I don't know why Lewandoski couldn't even make any goal, where he was from Bayern so they should know the defense of Bayern itself. But yes, Bayern's defense was verystrng. The loss of Barcelona 2 to Bayern really hit Barcelona. The club must try harder if they want to be in the top 2 of the group. Moroever the next match will be not esy also because they will also face Inter n which also compete to get the second position.
I was also surprised when I saw that Bayern Munich's defense was still very strong and was still able to score goals against Barcelona even though in possession of the ball it was bigger against Barcelona. But Barcelona had to accept defeat in that match because the home team (Bayern Munich) were really observant in taking advantage of their chances when the opportunity arose. So this is proof that Bayern Munich is still very strong even without Lewandowski in it.
