Idea for a fair decide system if "everything is tie" in Champions league

[Gabez Teh]

This Topic gave me the idea and Khris's comment was the the starting catalyst about my brainstorming of a fair decide system if everything are same in CL group after 6 rounds

Sooo as an above linked topic demonstrated there are several rare accidents like that when the system have to choose which team the lucky one

The system cannot:
- fit in the schedule: a play-off game or an extra penalty shootout
- fit in the visual engine: a coin-flip

what should it (we) do?

Here is my idea, instead of a lame coin-flip(luck factor bah) or a decision of which team has created first after network ID(lame too)

Every manager have:
-history
-all time stats
right???

Choose after (Champions league) game wins (firendlies not counting!) / all (Champions league) games!

for example my all time game statistic showing me i won: 292 times, draw: 28 times, lose: 16 times
292/336= 86.904 winning ratio...

That's it!

Good idea or good idea?
