I am poor in tanking. In season I want to tank, I just biased to use young players, sold old players, and offered zero win bonus. So I always failed. I could just finished in mid-table, and even never successfully avoid promotion.

Personally, I don't like to use illegal formation or meet teams with illegal formation. Using illegal formation or arranging players in non-preferred positions can improve the chances of losing games, but it is not guaranteed, especially the opposite team use similar strategy.

Sometimes, it is not easy to avoid promotion. In this season, there are at least 7 teams looked like an obsolete team, or teams aimed at losing games. In last game day (Round 6), there are 4 games ended with 10:0 or more.

Instead of tanking, I prefer to use a weak but young team to challenge for promotion or CL.
