With India and other nations perhaps they dont concentrate on football or olympic sports as much as they do Cricket or others. (Sorry Arka, I dont really know which sports India excells at!!
Nothing major except in cricket.
India was easily the best hockey team once upon a time, winning six back to back Olympic golds. In case you follow hockey, you'll know of someone called Dhyan Chand, who is regarded as the greatest player to have ever played the game. He was so good that Hitler himself requested him to come and play for Germany and offered him a high post in the Wehrmacht after seeing him play in the 1936 Olympics.
Needless to say, he refused.
And India struggles to perform properly nowadays. And hockey is very popular out here, definitely more popular than it is in Britain or Germany. Clearly, population is not that important a factor.
But who cares? I support Britain in all sports.
