Barcelona - Not bad at defending either.

Watch this video to see how quickly Barcelona try to win the ball back once they loose it. They call it the 6 second rule.

Watch the video at the 20 second mark. See how they loose the ball but but every single player quickly runs to make the team compact and tight together so that the opponents cant pass through them.

Also, notice how the player on line between their goal and the ball goes to pressure the ball to stop the ball being passed forward and slow the opponent down, and how many times it's a Barcelona player further up the pitch that comes back to pinch the ball.

Working as a team means we win the ball back quicker.

Winning the ball back quicker means less goals against us and more chances to score.

Less goals against and more scoring chances means more wins.
