Real Madrid star knows Germans will provide a stern test...
Alonso insisted that the European champions must ensure that their opponents don't open the scoring at the Moses Mabhida Stadium in Durban as they are a strong side who have shown an ability to score on the counter-attack in previous rounds.
"It's an historic occasion, we are very close and we cannot waste this opportunity," remarked the Real Madrid midfielder.
"Germany is a team above all else, they fight for the common good. Their collective spirit is more than demonstrated and it is also an attractive team. They will be a very strong opponent.
"When we go onto the field we pay no attention to history. We have to be motivated and pay special attention. We have to be solid and ensure they do not open the scoring. Germany showed against Argentina and England that they are well developed in scoring goals."
Now Alonso believes that La Furia Roja must make the most of their current crop of talent by delivering World Cup glory to compliment their Euro 2008 success.
"It is clear that Spanish football is going through a good time. We are a different group and we have been fortunate to get together but in the past there have also been great teams. Hopefully we can now enjoy and fulfil the dream of being world champions," he declared.
