Let me explain to you something. Let's disregard the fact that Nordeus didn't explain when teams are tied process.
Why do you want to finish 7th instead of 8th? Because you want to see the little screen that says "congratulations you got promoted"? Because believe me, finishing 7th may be the worst thing that can happen in this game. Why? Well for starters, you'll end up being fairly weak for your level and you'll have to spend more tokens trying to improve your team. Next, there will be no champions league, even after being promoted. If you finish 8th, your players will not lose a star and you can probably easily win the league with a strong team and get a Champions League spot for the following season.
So what's better, getting a miserable "7th" trophy in your cabinet and struggling next season or finishing 8th and getting another shot at the same level and most likely improving on your finishing position?
