I wonder where you looked at the statistics. I see that in the last 5 official games Bayern have 3 wins and 2 losses. This is a fairly close result that does not indicate an advantage of one of the teams. And in any case, what does this stats from 2022, 2011 and 2010 have to do with modern realities? Bayern has become much less strong since then, so I would not take this historical data as a basis for predictions.
I agree with you and although statistics are the basic reference in determining predictions, but if that is the reference then of course no team has managed to beat another strong team. Bayern Munich in the previous five matches against Inter Milan is also different from now because as far as I see they are slightly lower based on match statistics so it is difficult to say that Bayern Munich will beat Inter Milan.
The reality that I see is that Inter Milan's defense is much better and we can see how they played against Manchester City in the previous seasons in the Champions League, even though they ended up losing narrowly.
