Ah, so you too won the treble with a team that has clear weaknesses. Mine have been conceding a lot of goals, and I know that there is indeed a problem in defence. I sold my main defenders that were in the team for the past few seasons after last season finished, and made a mistake by selling the youth academy defender that came in too, and I struggled to get the defenders I was looking for, and hence, I had to do with what I could get for this season. My team have weaknesses in midfield too and it does not have a proper free-kick taker (one that would have a high percentage of free-kick conversion). The fixture list also was a hard one this season; many matches were set close to each other. Still, the team won the treble. In another season, you could have a much better team, a team with no weaknesses, a team with very good free-kick takers, and even get a better fixture list, in other words a team that should have more chance to win the treble, but still this team will only manage to win one competition (usually it is the league).
