But when you get everything right, it is a great feeling, especially if you stop a certain try.

Focus on the target area - the ball - and get as close to the ball carrier as possible.

Make contact with your shoulder on your opponent's thigh and position your head to one side of their leg.

Straighten your back and wrap your arms around the ball carrier's legs, pulling them down.

Land on top of the ball carrier - this is a very important point because it reduces the chances of injuring yourself.

Get to your feet as quickly as possible and get back into the game.
