Cup ranking incorrect?

[Buffs Mad]

it's not football that's the goal average general matters and only after the particular goal average between 2 teams in case of perfect equality

There's no error. Often leagues use goal difference but the Champions League is not a League - its a Cup. T11 uses the same rules as UEFA CL (as far as possible ie no country coefficient etc) - effectively when 2 teams are tied the head to head is treated the same as if they played a 2 leg cup tie.

Article 7 Afaik this was introduced to avoid the corruption/fixing/unfairness that sometimes happened - buying a big win from an eliminated team no longer has an effect

The new ones for the next cycle are out and look the same - but its now Article 17.
