Please, who can tell me the requirements and what it takes to start up a good Soccer viewing centre... and the best possible places to start it.

Is it a very lucrative business?? And what is the possible start up cost associated to it??

Like every business location matters when planning a viewing center. How is the location? Are there soccer loving fans there? If your answers is yes then you should go ahead.
Make sure the location is secure enough to guarantee security.
All you need is a sat dish, decoders, tables, chairs and so on. The hall must be big enough with windows to allow ventilation.

The driving force behind business is not how much you stand to make but how well you want to serve football fans with good soccer entertainment. All other things will follow.
Generally, I think viewing center business are profitable.
