I understand You've achieved everything and your level is so high right now. 4 more seasons July Fourth team will be 3 years old. If I was you, I would stop playing and buy a team full of 18* fast trainees, and tank that team for 8 months and then voila we would have a 9* team again later. In the mean time, I would do something else like traveling. That's what I will do after I win 10 trebles. Take a break from the game, go travel, and finish up my CFA Lvl III.
