Possible matches in round of 16

The teams will be drawn so a group winner plays against a runner-up. Teams from the same group, nor from the same country can play in this round. Taking these restrictions into account the possible matches have the following probabilities:

	Paris	PSV	Benf	Juve	Roma	Ars	Kyiv	Gent
Real Madrid	0	13	13	14	13	20	14	13
Wolfsburg	13	0	13	14	13	20	14	13
Atletico	13	13	0	14	13	20	14	13
Man City	17	17	17	0	17	0	17	17
Barcelona	13	13	13	14	0	20	14	13
Bayern	14	14	14	15	14	0	15	14
Chelsea	17	17	17	17	17	0	0	17
Zenit	13	13	13	14	13	20	14	0

Paris, e.g., have higher probability to end up with Man City or Chelsea because these team cannot play Arsenal. Similarly, Arsenal can only draw five teams as they cannot play Bayern, Chelsea or Man City and these five teams are equally likely at 20%.
