Your team is down by 8 or 9 pt. If you think your team is weaker, you certainly need to improve it first. I don't only mean improving quality. Simply speaking, you should find reliable players and a suitable formation.

To win league, the team should be consistent, especially if quality of opponents are close. Any team has bad days. You should try to make your team difficult to lose in these matches. Probably you need to attend matches and response to unfavorable situation (even though now I believe 'sometimes', 'in some situation' T11 try to simulate the matches).

If you can method to make your team much stronger than other team, e.g. farming/buying tokens => buy scouts /train players SA or to 6 star+, or tanking. You need not concern too much about other matter, just make your team strong & dominate every matches. If not, you need to make your team as strong as possible with limited resources, then at least winning matches you ought to win, and steal some matches you ought to lose. You/your team should be mentally tough to handle difficult situations.
