Hi,I'm on level 14,think that I've been winning my leagues for 7 or 8 seasons,but I haven't won a Champions or a Cup for 5 season.
I dominate my league,but I go out at any playoff phase.

This is because there are too many weak,illegal or bot-robot teams in our leagues,so your team freezes its performances (few goals scored and many taken also by poor opponents...),so it wins the league,but not the playoff matches againt better opponents.

I'm trying to change the situation,having much more friends on level 14,15 and also 16.

Now,I play friendly matches,so my team is well trained (expecially defenders and goalkeeper),and I see that my team's performance has improved in my League,and also friendly matches are good.

Next year,I'm expected to get many of these friends in my league,so it will become similar to a champions league,and i hope to be better trained for Cup competition.

Firstly,you should change old players who have already given all for the team
