I also adjust season target in this way in such situation. Moreover, I plan how to play against the super strong team. It is quite impossible to win the league if there is super strong team. But it is not too hard to upset them or even steal one or even two victories against them.
This was used to be my cycle of playing T11.
Starting a season as average quality 4 star team => gradually develop to a 5 star team during the season => promote to next level => becoming a 4 star team again.
If I excessively boost quality of my team, my team will be grouped with strong teams in next season. Moreover, in new season, there will be more players who are just added a new star and less players who are close to next star. As a result, it will be hard to sell players. The chain reaction will make my life much harder.
