Champions League and Cup are unfair competitions, especially if your team is near server's top level... You can get teams from level above or bellow, sometimes even 2 levels difference... If you and your opponent from 2 levels above spend the same amount of tokens, to buy 11 players at 99%, his/her team will be 40% stronger...

Years ago I suggested to them to make all teams to be in different tiers of the same level, with all players' overall dropping 20% every season... That would solve many problems, like tanking, up-selling, unfair CL and Cup... But, it seems they don't give a f**k...
