I know why I said that Bayern Munich has advantages of playing a home game because from the start of the game, Bayern Munich got a goal, and in a minute, Leipzig has equalised again.
To me this game will be more than we expected, although it might be, as you say, a draw game because the game has just started showing how it might end, so I will reserve all my discussion for the end of the first half and see what will happen, then I might predict the second half, but for now the game is getting tougher than I expected.
It's a goal!!! Bayern Munich just got another goal, which is making it 2-1.
When you are strong you don't even need anything like home advantage to win, so actually as Bayern Munich is wining Leipzig by 3:1 are we suppose to say that it was because of the home advantage?, however I'm not disputing your ideas because you are right by saying that but Bayern Munich is winning Leipzig because they are better and not only with players but also with there coach, Marco Rose may be very older in his coaching career than Kompany but it does not make him any better than him, however you would have lost if you had stake Leipzig draw because the fact that Bayern Munich was 2:1 against them wouldn't have make Leipzig to equalise and from this second half Bayern Munich will rain down more goals on them, so the unexpected you said will be more goals for Bayern Munich.
