Thks for your reply too. I believe I fully understand. There will be no effect to top 4 clubs while the 5th-12th clubs will participate a new competition.
I will feel fine to participate your new competition. But I prefer to take the chance to rest more if my team will finish below 4th. I think managing 1 more team is more flexible method to play more matches, because you can give up 1 team if you do not have sufficient time. Currently I am managing 2 teams.
