The game starts off at the kick off. The ball is at rest on the field. The ball pushed down on the field and the field pushes up with an equal force.

The forces cancel out as the ball does not accelerate.

The player kicks it off. When he does this he exerts a force on the ball and the ball exerts and equal and opposite force on his foot.

Because of this the ball moves instead of his foot going right through.

During the game, players often pass to each other with an air pass - a player hits the ball underneath, the force exerted on the ball also gets exerted on the foot by the ball with the same magnitude except in the opposite direction.

Fouls happen when a player directly hits another player. In this case, his foot exerts a force on their body, and the body exerts an equal and opposite force in his foot.

Often when the the ball is in the air, the player has to jump, the player, exerts a force on the ground and the ground exerts an equal force upward on the player.

The player jumps because of Newton's Third Law

The players also use their heads to hit the ball. Their head exerts a force on the ball and the ball exerts an equal force back on their head.

Players run by using Newton's Third Law too. As they exert a force diagonally on the ground, the earth exerts an equal and opposite force on their feet which allows them to accelerate forward. Also friction helps them move since it allows them to push off the ground more efficiently.
