Not sure if Inter can beat Bayern away... Although Bayern have not been playing very consistently lately, but they are stronger, more technical and younger than Inter's players... Even judging by the way they defeated Leverkusen in two matches and did not concede a goal you can think about their win... Of course Inter are also playing well, especially at home, but in Bayern I think they will not win...
2 clubs with contrasting playing styles but have extraordinary levels of strength. Bayern Munich will be much more aggressive while Inter as usual the Italian team often shows a tenacious game and is very careful in building attacks. Inter will be minimal in terms of attack but dominant in defense while Bayern Munich on the other hand is dominant in attack and minimal in defense.
