You'r now Lv 7 aparentlly.. On your time zone you'll be getting a wave of fast trainers at 6-7am in the morning.
Just get up few times in a week and u'll get the players you want to.
a Five star fast trainer on Lv 7 should cost like 16-20Mil. The higest price players would train alot faster
Just make sure you don't buy that donk free academy players, they price is about 9-12mil.
