Why can't we build our own football?

It is so fascinating to see the large number of football fans in Bangladesh. Just step out of your house, and instantly you will see flags of different participating countries of the World Cup, mostly Brazil and Argentina, all around.
This makes me wonder what will the Bangladeshis do, if Bangladesh ever goes to the World Cup? It would surely be a great pleasure for the football lovers of Bangladesh. So, Bangladesh government should invest in football to build a strong team which can participate in the World Cup Football in the near future.
