Developing legendary player

[LOS ABRANTES FC]

Hi guys, De Mattia currently looks like this:


Can you advice me how to boost his shooting ability, what training scheme to use not to loose to much od greens?

In your case almost all drills that train shooting have an high average.
The lower average is SET-P DELIVERY that is at 134%. Drills above 140% are no more efficient, and your player is already 22.
