Actually, it's the easiest, even though the probability of winning it is 1 in a 112, as you face only 7 opponents or even 6 if you make it to the final. Cup is also quite par to CL, since you face 7, despite the odds of 1/128. The league, even tho the odds are 1/14, you face 13 opponents. In cup and CL so can happen that 2 strong teams are drawn in the same tie, and it makes life a bit easier. I guess that's why I've won 2 Cups, 1 CL and 0 League (3-times runner up) in the past 7 seasons.
