It is always good to try something new just like the say that changes is constant in life,the most interesting part of the matches will be played in U.S.A,while the Group stage will be played in the three different countries, I guess,there might be a certain number of people that will be accepted in the world cup.

We shouldn't think that using the three country will be a big challenge in the tournament,we will have 48 countries to be present in the world cup,the population will be more than those that went to Qatar because all the 48 countries fans and supporters will love to go from different part of the world. Like said USA and Canada have more population than Qatar and,only one country will not be able to contain these countries because on their own,they are already have large population.
