The science behind Lionel Messi free-kick

Free-kick is one of the toughest things in football. It’s require pin point accuracy with enough power to put ball in goal post. In the football history only few players had this type of technique to take free kick.

So know we try to understand what is reason and tactics behind taking free kick by Messi

Report suggested that Messi changed his way to hit ball in training early on, using plastic plate as a barrier between him and the goal.

When Messi taking free kick that time his leg has an angle of 50 degrees. Entire shoes plants on the ground before hitting the ball, it gives stability and control.

The department of physics at the university of Barcelona said : “ he uses the Magnus effect to find his consistency from free kicks.”

According to the report, “ the pressure on the lower surface of the body(ball) is greater than the pressure on the upper surface, resulting in a force curve trajectory of the body.

Messi is able to score free kick anywhere, and he told :

"Yes. To be honest, I like to hit the ball over the players' wall but from time to time I like to mix it up a little bit so that the goalkeeper doesn't know where I'm going and I want to keep him confused until I kick." 

"I think for that reason I like to keep the goalkeeper in doubt."

Barcelona Star Ivan Rankitic told : “ sometime we celebrate free kick goal earlier because we feel like today Messi will put ball in goal post.”
