Barcelona forward and Argentine national team player Lionel Messi is considered one of the best soccer players of all time. Learning some Messi skills might not win most players the Ballon d'Or, but they can significantly improve a player's performance.
Among his other talents, he is an exceptionally good dribbler, and striving to be as comfortable with the ball as Messi is a good goal for players who want to develop Messi skills. When watching a player like Messi, it is almost as though the ball is attached to his foot by invisible string, but this is simply a testament to his excellent ball control. Messi's footwork is not always as flashy as that of other players, but his ability to move and control the ball past multiple defenders is. People use words like "magical" to describe how deftly he maneuvers into enemy territory and with ease.
This means that one part of developing Messi skills means working on speed and agility. Because of that speed and agility, often Messi is just too fast for anyone to keep up with. However, he has a few flashier moves as well. For example, the lift, step and go requires the skillful use of the inside of both feet to knock the ball past the defender. The initial feint fakes out the defender, and the player is able to escape with the ball.
Messi skills will make players faster and harder to tackle and will lead to a big overall improvement in play.
