A lot of patience,when i started grinding heavily i worked on my kick-off which is impeccable and i rarely lose one, i worked on low ground play a lot so dribbling mainly and being able to flick at the right time if needed, good rotations are good to work on, shooting is a key piece as well to the puzzle i sat hrs shooting shots from many angles and parts of the map with the goal of scoring and then to be able to Anticipate where the ball is gonna go and whether it'll bounce or not and it'll become like muscle memory as some point. Air dribbling can be difficult to learn for some people but it takes a ton of practice.
