Developing legendary player

[pcmacdaniel]

Congrats on your treble last season

As for how to best build a legend!

First and foremost, the current training system is terrible. I'd wait until the release of TE 2019 to pursue any serious power-training.

Acquire a 3* 18 year old player.
Make sure that player only knows one position (Do not add a second position).
Don't play him in matches until age 20+

"Playing a young fast trainer in matches means alot of skill points are acquired, and they will be added at random. This means they get added to the gray skills, which will subtract from your ability to train the most important skills to high value. Keeping the youngster out of matches means that the skill points will not be added to the less important skills at random."
.
Target train only the white skills at first, specifically the key ones.

For a player to get towards legendary status, you can't let the gray skills get high. As skills move up in value, the growth rate slows down. Anything above 140% is extremely slow, so need to use drills that train both gray and white skills to keep the growth rate fast. A 5* player acquired from the transfer market, unfortunately the gray skills are too high for player to be trained efficently.
