It was a rude malicious foul, not a tackle against the ball but at someone, and such a tackle was irregular and unreasonable.
Let's take a look at the tackles that are properly regulated without hurting the opposing player.
With the correct tackle, the lower body should be completely pressed against the ground, and then use the foot closer to the ground to block the original route of the ball.
This can generally block the ball, and the player who originally carried the ball will choose to pick it up, avoid the tackle, and pay attention to the other foot when tackling the ball cannot be lifted.
Tiptoes should be retracted when touching the ball, so that they can intercept the ball without causing harm to the players.
If straightened, it may cause the ball to leak.
If the tackle is broken from the side, try to aim and predict the direction of the ball and then shovel it down, and shovel the ball to the outside.
The shovel must be cautious, otherwise it is easy to eat the fake action of the opposing player and save it.
When you are alone, you can also do tackle training.
