This video focuses on your ability to bring the ball under control when it travels to you in the air.
This is very important to be able to deal with the ball quickly and effectively when it leaves the ground with different parts of the body.
Looking at control with the feet, knee and chest to allow you to prepare yourself for however the ball travels to you.
Some of the greatest goals have been started through immaculate control; think Bergkamp at the 1998 world cup (definitely search this if you don't know it). It also sets you up for the ability to judge the flight of the ball out of the air needed for skills like volleying.
