In the guide you mention that you in the CL will meet your own league or 'very close to. However I am level 12 and meeting a level 13 in next round (first knockout stage) and he can assemble a 11 man squad with an average above 88 while the strongest we can buy using tokens in level 12 is 84. I would somehow claim that this has to be a bug because he is actually stronger than the strongest level 12 team can ever be.
