tell me is my team good enough for the next season what should I buy??

[Tactician]

With that team you can't go for the treble (because of the cup).

I almost won the Cup this season despite not using the so called 'strategy'. There were opponents from levels above, but this was not the problem as long as other things other than tactics and quality were not significantly affecting the outcomes. The problem was a team from the same level as mine as discussed to you in the past few days.
