BTW, just noticed that my cup opponent is indeed at 30.9 strength and is L5, but it seems like he has abandoned his team. Am I going to have any chance against him?
If you attend both games then I believe a victory for your team is more than possible, the possession bonus could tilt the game in your favour, I played Level 16 away and won 3-2 and got through on away goals in the 89th minute last season.
