Tackle is very important part of football, because this will allow you to get the ball off the opposite team. If you cannot tackle you would be running around and hoping to intercept the ball from the opposition. Tackling is part of o competitive football.

The tackle starts by stamping leading non-tackling foot on the ground. Use the inside of the other foot for tackling, not the toe.

It is important to be committed and put full weight behind the ball,

 to get the head down over the ball.

Timing is very important. A good time to tackle is when your opponent looks down at the ball.

Try to tackle when your opponent is off balance, or shows too much of the ball.

The sliding tackle or recovery tackle is an important skill requiring precise timing. It's not just defenders, who need to be able to tackle. Even forwards should be able to make a sliding tackle. The football team that can tackle better can take much of the initiative away from the opposition, denying them space, time and putting them under pressure.

It's best to tackle with the foot that is furthest from the ball. This gives you extra reach, and reduces the chances of giving away a foul. The sliding tackle is best made from a square position with your leg going out to the side rather than straight in front of you.

 The key factors for any player are to watch the ball carefully, and synchronise yourself with opponent, try to anticipate his movement and then do your slide tackle.

 You have to make sure you make contact with the ball, and the whole movement is not clumsy, hence speed of operation is important.

Exercise

A player (winger) will run towards on the touch line towards the corner flags,  the defender slightly later will chase after him, and tries to make a sliding tackle putting the ball into touch. The winger must try to reach the touchline without being tackled.
