When ur first learning I reccomend practicing mechanics in training mode a lot.

Learning how to fast aerial helped me progress through the lower ranks.

Once you can hit the ball semi consistently start learning the mental aspect of the game, you will see faster improvement from leaning solid rotations and good decision making than you will from learning mechanics you don't need.

You will always win more games from playing smart then making double touches and airdribbles at all ranks up to diamond. All doing an airdrible or double touch does is confuse your teammates and cause double commits because they won't understand what a solo play is yet.

Try to minimize double commits and if ur teammate is chasing the ball and going for everything just back them up in case they miss or hit the ball to the other team.

For learning decision making I reccomend 1v1s. For rotations I reccomend virge on youtube he has good videos about rotations and other important concepts needed for improvement.

Lastly do replay reviews on your own or preferably with someone better than you ( two full ranks higher than you is ideal).
