Yes, I remember when Bayern lost away to Feyenoord with a big score, but made a crazy amount of attacks, but could not score a goal... But Bayern at home is a completely different team, in Munich it is very difficult for any club to play against the hosts... I think that Inter will definitely have difficulties to at least draw in the first leg...
Inter have shown in recent seasons that they cannot be underestimated and that they take the Champions League very seriously. But Bayern are recovering this season, they can play very well in some matches, but sometimes they can lose even with total dominance, as was the case with Aston Villa, or even with weaker teams in the Bundesliga they also sometimes lost points and were almost helpless, as was the case in the match with Mainz. Inter is much more stable, this can be significant, equal teams, here I can not single out a favorite.
Bayern Munich will play Inter Milan at the Allianz Arena the home ground of the Bavarians and literally, Bayern Munich has been unbeaten at home in the Champions League games so far which means that they will still keep to it hence Inter Milan though a very strong opponent but not when they are matched with Bayern Munich that got more Champions League records than Inter Milan. Bayern Losing to Aston Villa and Mainz shouldn't be used as a yardstick to measure with their game against Inter Milan, after all, Inter Milan is superior to Aston Villa and Mainz. Inter Milan is a very stubborn side with some skillful and tactical strikers but Bayern Munich's attackers won't also relent, however, i think Bayern Munich will have this one.
