Why are we more likely to get Inter than Club Brugge? Presumably because there are more Italian clubs in the second seeds?
Club Brugge will be lower odds because they are only 1 of 4 teams that Bayern can face, so that makes them drawing each other more likely and us less likely. Napoli also have better odds of facing them, 1 in 5.
That's why Liverpool-Bayern is so high because they can both only face 4 teams, and 1 of them is each other.
