First touch; receiving and or trapping a ball while in play. 

First touch in soccer is in reference generally to trapping or recieving a ball, but it should also be thought of in reference to winning loose balls or even intercepting passes. Having a good first touch in all these cases can set a player apart and change the pace and level of a players game. It is an essential part of the game that is often overlooked and/or rarely focused on when developing fundamentals. Developing a first touch that is soft and precise is important in controlling a ball or
gathering a loose ball.  Developing this skill will buy time on the ball as well as increase  speed of play. 

A great way to develop a first touch while training by yourself is by juggling. Juggling offers players the opportunity to execute quality touches in large quantities in abreviated training sessions which will enhance performance, confidence on the ball and increases overall skill.

We will call this Three touch and a knock: Juggle the ball three
times and then kick it 10 to 15 feet in the air, control the ball with one soft
touch, trying to keep that touch below your waist, use one to two touches to
adjust and compose yourself, then knock it 10 to 15 feet in the air again.
Repeat this process. Work on controlling the ball with your first touch after
you have “knocked” it into the air, then use the other touches to
manipulate the ball so you can “knock” it accurately into the air
again. Progress to a three touch rotation (Knock -control- touch – knock,
repeat..) and then a two touch knock-control-knock, repeat.  This exercise will
help to develop “first touch”.
