I only keep 7 main players in my team whom I train to 140% every season and keep in my squad 7 seasons on average. These players are either 119% recommended players or 40% auction players who I train to 140% sometimes Academy players.

I only use scout players to boost my quality I will never power train them they usually spend 3 seasons in my team. I use negotiations sometimes to fill some holes in my squad I'll use them for just 1 season. 80%+ auction players are used to feel my bench and I never go for the top rated 90-99% auction players I usually spend just 1 token when I'm signing a player from auction
