Since I just promoted to level 3 I dont have many seasons experience on whats common or not...
But I almost had the treble with 26-0-0 in the league on level 2.
Lost the cup final to a stronger opponent, but reaching that final was already an achievement due to a lot of very strong competition I think!
I am looking forward to see how strong the league opposition is this season. CL is stronger than last season (relative to my team level) and the cup seems to be always VERY tough...
Good luck in your new season!
