Leo Messi is the best player because of how lethal he is at dribbling, and how ultimately dangerous he is with the ball at his feet. For example, his acceleration makes him exceptional when it comes to speed.
which helps him succeed in dribbling through different opponents and makes defenders struggle when tackling him.
He keeps multiple defenders off balance depending on the situation with body feints.
Often, you may find yourself unable to catch up with Leo as he mysteriously beats you due to a shoulder one time and then cuts you down with speed on another occasion without shirking the ball in the slightest!
