making a killer striker(9star) need help

[July Fourth]

interesting thread. is this power training cheaper compared to personal trainer?

Yes with trial and error I worked out the power training will get you around twice as many skill points that using personal trainer, It just takes a good bit of your time constantly training players for a few days.

With 22/23/24 year olds I got 139 skill points from 350 packs (322 tokens), the most skill points you can buy with personal trainer with 322 tokens is 80. but thats usually when upgrading players from like 4*/5*, for getting from 8* to 9* the personal trainer was asking for 80 tokens for every 8 skill points.
