CHAMPIONS CUP ??

I had 2 wins in champions cup finished 2nd in League phase
Yet the team finishing 3rd got through to the knockout stage
WHY,
what's the point in this tournament if you can finish in the top 2 yet the team in 3rd qualifies.
Anyone else had that happen to them ????
Same thing Happened to my team twice so far.
2nd time in this current tourney,
finished 2nd, but not through to next stage as the same thing happened, 3rd placed team went through.
Been there as well just another reason why I've had enough & leaving at the end of this season
