So we are both "treble frustrated" as I won the 2 cups and failed (unless a huge miracle happens in the last two games) in league. First time this happens to me. But as I mentioned in various threads, I think there is something biased in leagues recently (at least in the last 4-5 seasons). My team, who was absolutely unstoppable in both cups, struggled in almost every game in league against weaker sides. We'll see next season !
The nearest Palace Casuals have been to a treble was their Season 22 - 2nd in League, lost in CL Final, won Cup Final.
They also had a season (17) under their previous name where they got to both Finals, won the CL but lost the Cup Final, and struggled to 8th in the League, but still went up a Level for the next season.
Any formation or tactics advice given is based purely on experience with my teams...
