So, I tanked the last season, building up the team quality and only buying 2 players. I'm still trying to win a cup that I still miss. Yesterday at the start of the season I realise I ended up in a cup 1 level higher than me! I still qualified by sheer luck (3-3 home and 2-3 away) and won today (from 3-1 to 3-4), but I won't have luck for much longer.
If only I knew before
However I still think the cup is too subtle and unfair, I could almost never do anything great.
