 Person1:       Which team do you think will emerge with the last laugh in this World Cup ?  
 Person2:I wish it could be Germany . But it seems they are not in a very good conditions .  
 Person1:        No , they aren't . They had a hard time in the group stage and only sealed a sit in the eighth-finals with Wallack ' s header in the final three minutes . Just think , group A consists of Austria , China , and Saudi Arabia , all of which are minnows .  
 Person2:It seems they've been out of luck since the beginning of the event . Their shots hit the woodwork as many as six times . Oh . my goodness ! I'm afraid the team is under a spell .  
 Person1:        Well , at least the Germans have demonstrated a very good ability to control the midfield . They recorded a total of 62 tackles in the match against Austria . And they to be endowed with perfect positional sense . I think that will give rise to scoring chances sooner or later .  
 Person2:I agree . Eeven though German attackers are not good at dribbling past opposing defenders , they breach the defensive line through quick movements to the right attacking positions and through accurate , well-timed passes .  
 Person1:        That's why I still have very high hopes for the team . Now that the tournament has proceeded into the knock-out stage , the Germans will probably make it through to the finals .  
 Person2:Yes . They have a good reputation for their tenacity and discipline , especially in vital , decisive encounters .
