Hi,I'm at level 22 and I see similar situations for Chinese,Japanese and Thailandese managers,even if not having so many stars (maximum 7 or 8 stars players referred to level 22 evaluation).

When you have 2 or 3 of these teams in your league:

1) try to be regular vs other teams that are supposed to be more affordable,while the top teams are fighting among each other, not
to be so far from them

2) don't give up trying to face those team in the best way you can; you might be surprised if your team has a good organization and efficient play (beyond the opponent you're facing and consequent result),since strong teams are sometimes left alone by their managers.

If they're actually too strong for you,maintain the first position usefull to be promoted.
