Bayern Munich won at the Celtic, but this was also hard fought win for them because Celtic done good resistance and in last few minutes things were completely looking for having draw, but Bayern Munich is surely big club with enough quality and sources which give them good success and advantage in this game.

This was Celtic's home match. Naturally Celtic played well. Every team that qualified for the play-offs is strong enough. So now every match will be very competitive. I have seen the highlights of every match yesterday. Every team played well enough. Although we consider Atalanta and Milan as favorites, these two teams lost.
We expected to see an attacking gameplay from Munich. But Bayern Munich could not play a completely attacking strategy. Bayern Munich players managed to take a total of 10 shots. Munich's attack was strong, so they were able to score two goals.
Bayern Munich's performance needs to improve further if they want to qualify for the champions League final. If they perform like this, they will not be able to win against Liverpool, Barcelona or Madrid.
