Guys, thank you for the additional information.

@ Hunter
now here comes the most important point; remember why you are tanking - tanking for resources not for titles.
so don't buy FTs now. buy anyone who won't cost you more than 3 tokens. make an average team and don't rob someone else from the titles he deserve.
Tanking was not an option for me, since I am a title hunter, but I'm thinking about starting again from lvl 1 and maybe I could spend first two seasons for resources - greens, tokens, etc. But I will miss CL titles

@ Rizla
For example tackling and agrresion is low enough so you can train him with 1to1 finishing,warm up,carioca,hurdle jumps etc...
This is a good info, works well. But, it gave me another thought, that having players with 3 different positions is not that best option, since we get a lot of white skills and only few of them grey, and then the players are mediocre rather than star player on his positions. Will see with my new academy FTs for future results.

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.
I will see this option - but this one will require a lot of greens to develop player from 3* for three seasons up to 140%. So at first I need to harvest almost full season for that - I don't know if I will be that patient, not to spend them

But I know what you mean. And maybe will give a try for one winger...

Nice ones.
