coach sylvia knight doesn't want to leave anything to chance.he past two months she's been putting the team through their paces. they've had to give everything, on and off the pitch. the german women's side has never been so fit and so well prepared ahead of a world cup tournament. >> i can't say we've enjoyed the preparation bays it's really hard-going. but we have our eyes on the goal. we know why we're doing this. and it is worth the effort. we can take the pain because we know we'll be in top shape. and we'll have to give more than 100% in order to remain top as the tournament kicks off. >> 21 players in top form. but they'll need a lot of discipline and hard work to defend their title. they expect cirrus challenges from the u.s., sweden, and japan. they're hoping to save the best for last. >> i'd like to reach the final and play against brazil again. if i could have one wish, brazil would be cool. >> the german women must prevail five matches to get through to the final and then win. the team would love to raise the world cup trophy in fron
