It doesn't matter how many goals you score; one goal is enough if you don't let one in your net.
You never lose a game if the opponent doesn't score.
Of course you don't want to concede a goal in any game.
If you never concede a goal, you're going to win more games than you lose.
If you like soccer, then welcome to America. See, our country already has entertainment so watching people chase a ball for four hours to end 0 - 0 is not enjoyable - unless, of course, the bleachers collapse and half of Europe dies.
After a goalless first half, the score at half time is 0-0.
The fans do not want to see 0-0.
I think if you're not conceding so many goals, it gives you a great platform to win games.
