It doesnt bother me to see someone trying to Fstyle if they have never played ball before.
In actual fact, its their problem, I think having a playing background is an edge, so theyre missing out.
And I have seen some very good players that have terrible juggling style, its quite sad to watch.
These well-renowned players have such great control when the ball is on the ground.....but when it comes to keepin the ball in the air, they suddenly lose all control over the damn ball ! Obviously there are some exceptions.
