I sees this game more like a banana peel to Bayern Munich if they feel too complacent of how it has really been easy in putting dortmund away, mostly at the alliance arena, but if they don't feel complacent and they decide to take this game very serious, them I am quite positive that they can win this game very well, considering the fact that their performance of recent have really improved, so just as favourite as they are now, it wouldn't be ok at all to their fan if they can't win this game, so it's a must win game for Bayern Munich, to build more confidence ahead of their upcoming encounter between them and arsenal.
This match should not be difficult for Bayern Munich if you look at Dortmund's current performance, because in general Bayern Munich's strength is still better than Dortmund even though both are still in the UCL this season. But for this week's home match, the home team should be able to win, even though this will of course be very detrimental to Dortmund because Dortmund will lose their top four position if they are unable to win this week's match at home to Munich.
