I 'm buying young fast trainers and keeping them for 5-6 years.
I buy about one young scout/list player every season and keep them for 3-4 years (in high quality, 6*).
Also fill the blanks with a couple of 5* veteran players.
I 'm starting the season with a 5* team and with training and participation, at the mid/end of the season I have a 6* team.
- the higher if I can, training them without spending much greens.
This quality is enough to win any title.
