Not sure how the cup is worth winning compared to CL since the monetary gains from CL itself is bigger than Cup. Completing the group stages will earn you much more than your run of 6 games in the cup.

I usually just send my weaker teams in the cup or use it to test out new buys early in the season. Probably why I'm always out in the first or 2nd round!

I've joined the Hall of Shame for this season
First Leg 2-2
2nd Leg 0-1 loss AT HOME (goodness!)
